How To Update ‘A’ Record IP Address On Domain Name?

Leave a comment

An A (Address) record is a type of DNS (Domain Name System) record that links a domain name to a specific numerical address of the server where the website or service is hosted, this is called IPv4 address.

So when you copy the shared or dedicated IP address of your hosting and paste it in the A record of your DNS, it will ensure that when someone types your domain name in the web browser, it will open your website by resolving to the correct IP address of the server that is hosting your website.

To update your domain name’s IP address in the A record on Sangkrit.net, you will need to follow these steps:

Step 1. Log In to Sangkrit.net

  • Visit System.Sangkrit.net.
  • Click “Sign In” at the top-right corner and enter your account credentials.

Step 2. Access Your Domain Settings

  • Once logged in, click on your username and select “My Products” from the dropdown menu.
  • Scroll down to the “Domains” section.
  • Locate the domain you want to update and click on “DNS” next to it to manage the DNS settings.

Step 3. Find the A Record

  • On the DNS Management page, scroll down to the “Records” section.
  • Look for the A (Host) record, which should have a value like “@” under the Host column and your current IP address under the Points to column.

Step 4. Edit the A Record

  • Next to the A record, click on the pencil icon to edit the entry.
  • In the “Points to” field, enter the new IP address you want to assign to your domain.

Step 5. Save Changes

  • After updating the IP address, click Save to apply the changes.

Now allow DNS propagation time as changes can take some time to propagate across the internet, usually within a few minutes to 48 hours.

Following these steps, you can easily update your domain’s IP address in the A record on Sangkrit.net.

How To Use Subdomains On Different Hosting Accounts And Different Nameservers?

Leave a comment

Just like domains you can use custom name servers on subdomains too for domain names registered at Sangkrit.net. This way you can use subdomains the same way you use domains for hosting new websites, as addon domains on any web hosting option or server.

You can use these subdomains on any VPS, Dedicated Server, or any Shared Hosting plan just like the regular domain names.

How To Point Subdomains To Custom Name Servers?

Login to your Sangkrit.net account and follow the given steps:

  1. Access your Sangkrit.net domain manager, the one you see on MY ACCOUNTS page
  2. Select your domain and click the Manage button
  3. On the DNS configuration page scroll down and click the “Add Record” button
  4. Select a new “Nameserver” entry on the Record Type field where the “host” will be your subdomain name which you want to point to custom name servers. Use the proper nameserver naming format or Sangkrit.net will kick an error. “Points to” will be the name server such as NS1.SANGKRIT.net dns-subdomain
  5. Then you can add a new record with the same host and this will point to NS2.SANGKRIT.net (if required).

That’s all. DNS propagation takes some time and then you would be able to use this subdomain on your hosting or server by adding it as ADDON DOMAIN on cPanel or wherever you like.

Alternative Method: Alternatively you can add A record (instead of NS Record Type) pointing to your server’s or hosting’s shared IP address.

How Nameservers Are Configured On Dedicated Server & VPS?

Leave a comment

Nameservers are used for masking IP addresses to domain names.

However, you can directly mask an IP address to different records of your domain name to make it functional. But doing a nameserver setup lets you enlist all domain records in your nameservers to use them on your domain (website & email, etc).

Configuring Nameservers On Dedicated Server (Via WHM):

  1. Log in to your Sangkrit.net account
  2. Open the Products page and click the Servers tab
  3. Click Launch (Next to the account, you want to use)
  4. Click Manage Server (WHM) 
  5. Click Proceed

Once, you are logged in to your server, follow these steps:

  1. Navigate to WHM’s Nameserver Selection interface via WHM -> Home -> Service Configuration -> Nameserver Selection
  2. Select the desired nameserver software
  3. Click Save

To configure your default nameservers:

  1. Navigate to WHM’s Basic WebHost Manager Setup interface via WHM -> Home -> Server Configuration -> Basic WebHost Manager Setup
  2. Enter the desired nameserver names in the text boxes
  3. Click Save

Remember, the name must prefix, a dot (.), and your domain. For instance: ns1.example.com and ns2.example.com.

Next, you will need to add the IP address to your nameservers:

  1. Navigate to WHM’s Add a New IP Address interface via WHM -> Home -> IP Functions -> Add a New IP Address
  2. Here you may either enter the main IP address or the IP address range (if you have one) in the New IP or IP range to add a text box
  3. Enter the subnet mask in the Select a subnet mask for the IP or IPs above to use the text box
  4. Enter any IP addresses that you wish to exclude in the IPs and IP ranges to exclude from the range of new IPs text box
  5. Click Submit

Creating A or AAAA entries on your nameservers:

  1. Access WHM’s Basic WebHost Manager Setup interface via WHM -> Home -> Server Configuration -> Basic WebHost Manager Setup
  2. In the Nameservers text box, click Configure Address Records
  3. Update the IP addresses in the appropriate text boxes
  4. Click Configure Address Records
  5. Click Close

Repeat the same steps for each of your nameservers.

For creating entries of your hostname:

  1. Again, move to WHM’s Add an A Entry for Your Hostname interface via WHM -> Home -> DNS Functions -> Add an A Entry for Your Hostname
  2. Enter your server’s IP address in the text box
  3. Click Add Entry

Next, you will need to register the same nameservers on your Sangkrit.net account from your domain management section. You will need to change the nameservers of your domain to use these new domain nameservers.

Simply log in to your Sangkrit.net account and follow these steps:

  1. Visit your products page, in the Domains heading, click Manage
  2. Locate the domain for which you wish to set up your nameservers
  3. Click the settings icon and select Manage DNS.
  4. Click the Settings tab and click Manage under the Host Names setting
  5. Click Add Hostname and enter the primary nameserver’s name (for example, ns1)
  6. Enter the primary nameserver’s IP address in the IP Address text box and click Add.
  7. Now, repeat the same steps for your secondary nameserver, this time use another nameserver such as ns2
  8. Click Save. Then, click Edit Nameservers and select Custom option
  9. Enter the full names of your two nameservers. (For instance: ns1.example.com and ns2.example.com)
  10. Click OK and then Save your changes

That’s it. The DNS propagation takes some time to spread the domain’s new DNS records across the internet. So, allow it twenty-four hours and your settings will start to work.

How To Configure Reverse DNS On Your WHM Server?

Leave a comment

DNS i.e., the Domain Name Server also known as Domain Name System is the hierarchical and decentralized system of identifying systems reachable through the Internet Protocol networks.

It works by looking up your website by finding its domain name and then locating its associated IP address. Whereas, the reverse DNS first looks up for an IP address and then locates the associated domain name.

The reverse DNS is actually a process that involves the conversion of an IP address back into a domain name. While the traditional DNS translates domain names (like – example.com) into IP addresses (like 132.0.3.1), reverse DNS does the opposite – it translates IP addresses into domain names.

The Reverse DNS is mainly used for:

  1. Email Servers: Reverse DNS is commonly used by email servers to verify the legitimacy of incoming emails. Many email servers check if the reverse DNS entry of the IP address sending the email matches the domain from which the email claims to be sent. This helps in preventing spam and identifying potential sources of malicious or fraudulent emails.
  2. Network Troubleshooting: Network administrators use reverse DNS to understand the domain names associated with specific IP addresses. This can aid in troubleshooting network issues, identifying the source of network problems, or verifying the ownership of particular IP addresses.
  3. Security: Reverse DNS can provide additional information about the server sending traffic to your network. It’s used in security measures to analyze and filter incoming traffic based on the domain names associated with the IP addresses. This can be helpful in identifying and blocking potentially harmful or unauthorized access attempts.
  4. Logging and Analytics: Some systems and applications use reverse DNS to log the domain names of incoming connections, providing more meaningful information in logs and analytics.
  5. Online Reputation: Some online services use reverse DNS as a factor in determining the reputation of an IP address. A well-configured reverse DNS entry can contribute positively to an IP address’s reputation, while a lack of reverse DNS or misconfigured entries might affect it negatively.

Setting up reverse DNS involves creating a PTR (Pointer) record in the DNS zone files, and linking an IP address to a domain name. This PTR record helps establish a connection between the IP address and the domain name it represents.

It’s important to note that the accuracy and presence of reverse DNS entries can vary. Some organizations maintain proper reverse DNS entries for their IP addresses, while others might not. Additionally, the process of setting up and managing reverse DNS might involve coordination with the hosting provider or internet service provider.

But at Sangkrit.net you don’t have to worry about that, you can easily setup the reverse DNS by following a few easy steps, and the round-the-clock online support is also available to help you in case you feel stuck anywhere.

How To Setup Reverse DNS?

At Sangkrit.net, you can easily set up a reverse DNS (RDNS) lookup for your Dedicated Server. To start, simply login to your Sangkrit.net account and follow these steps:

  1. Visit your My Products page
  2. Click Servers
  3. Next to your server, click Manage
  4. Enter the domain name you want to be associated with the server IP address, in the DNS record field
  5. Now click Update

The system will start an automated process of completing the reverse DNS setup. This can take up to 48 hours for the changes to propagate to your server.

If you have multiple IP addresses on your server, repeat the process for each IP address you want to set up Reverse DNS for.

Now the traditional process of setting up reverse DNS is a little bit different, you may follow that also:

  1. Log in to WHM: Access your WHM control panel using your administrator credentials.
  2. Navigate to “DNS Functions”: In WHM, search for or locate the “DNS Functions” section. This is where you’ll manage DNS-related settings.
  3. Edit DNS Zone: Under “DNS Functions,” click on “Edit DNS Zone.” This will allow you to modify the DNS zone files for the domain.
  4. Select IP Address: Choose the IP address for which you want to set up Reverse DNS (PTR record). Click “Edit.”
  5. Add PTR Record: In the DNS zone editor, you’ll see the existing DNS records. To add a PTR record, scroll down to the “Add New Entries Below this Line” section.
  6. Enter PTR Record Details: Fill in the following information to create the PTR record: Name: Enter the last segment of the IP address in reverse, followed by “in-addr.arpa.” For example, if the IP is 192.0.2.1, the name would be “1.2.0.192.in-addr.arpa.” TTL: Set the Time to Live for the record.
  7. Save Changes: Once you’ve entered the PTR record details, click the “Save” or “Save Zone File” button to save the changes.
  8. Update DNS Zone: After saving the changes, WHM will update the DNS zone file with the new PTR record.
  9. Verify PTR Record: You can verify the PTR record by using the “dig” command in the terminal or through online DNS lookup tools. It might take some time for the DNS changes to propagate across the internet.

You should also know that, when you run your own email server, and configure DNS to point to your domain name, there are some servers that are going to reject emails from IP addresses when not having an rDNS. The reverse DNS also helps when you need to troubleshoot your network while running a traceroute etc.

Reverse DNS is a useful mechanism that adds an extra layer of information and security to online communication and networking processes.

How To Map Domain Names When Name Servers Don’t Work?

Leave a comment

Domain mapping is a process that allows you to use a domain name on your website or web service on any hosting option such as cPanel Webhosting, Plesk Windows Hosting, Webhosting Plus, VPS, or Dedicated Server. It is generally done by updating the name servers on domain names to point to the server where you are hosting or planning to host your website.

Sometimes on self-managed servers and advanced hostings, the nameserver needs complex configurations to work, these settings might not be easy for general users. If adding custom name servers doesn’t work for you, you can set your domain name to work simply by editing its DNS zone.

In this case, you don’t need to edit or use custom name servers but make some changes in the DNS zone file and it will start working with default nameservers provided during the time of registration.

The first thing you need to do is log in to your VPS or Dedicated Server and copy its IP address which you will find on the My Products -> Servers -> Manage page. If you have a hosting, the IP address would be visible on the cPanel’s information page.

Once you have the IP address the next step is to log in to your domain account and click the ‘Manage‘ button to open up domain details.

DNS 1

Select the DNS Zone File tab to edit your domain’s zone information. Click the ‘Add Record‘ button present in the zone file section and add records as shown in the following screenshot.

DNS 2

The examples:

  • Hostname – www, record type – A address, ***.***.***.*** (IP)
  • Hostname – @, record type – A Address, ***.***.***.*** (IP)
  • Hostname – *, record type – A Address, ***.***.***.*** (IP)

Don’t forget to replace the ***.***.***.*** with your server’s IP address. You can add records one by one by clicking the ‘Add Another’ button. Once DNS records are added, save changes, log out, and wait for the DNS propagation.

DNS propagation refers to the process by which changes made to Domain Name System (DNS) records are distributed and adopted across the internet. When you make changes to your DNS records, such as updating the IP address associated with a domain or adding new records, these changes need to be propagated to DNS servers worldwide to ensure that internet users can reach your website or services using the updated information.

This might take up to 24 hours to complete but generally at Sangkrit.net, it starts working for you in a few minutes.

Enhance Website Availability By Implementing Secondary DNS

Leave a comment

You can prevent downtimes and keep your business constantly online by configuring an additional set of nameservers on your domain name. This secondary DNS server serves as a backup to the primary server, ensuring that domain name resolution remains available even if the primary server experiences downtime or becomes unreachable.

What Is DNS?

DNS is the Domain Name System which is also known as Domain Name Server. Its work is to convert alphabetical names called Domain Names into numeric IP addresses so that the end user can simply remember the domain name and not the IP addresses.

For example: What happens when someone gives you his contact number? He tells you a set of numbers. If the domain name system wouldn’t be there on the internet then people would have to give numbers instead of domain names just as it happens in the case of mobile numbers. DNS is the spine of the internet, it works everywhere on the web.

To access DNS you simply need to sign in to your Sangkrit.net account and follow these steps:

  1. Visit your Domain Portfolio
  2. Tap on your domain name
  3. Select Manage DNS
  4. Manage DNS for any domain

What Is Secondary DNS?

Secondary DNS offers you an additional set of name servers to keep your website live in case primary DNS is down.

It is a backup or redundant DNS server that works in conjunction with the primary DNS server to provide domain name resolution services.

The primary DNS server is responsible for maintaining the authoritative DNS records for a domain, translating human-readable domain names (like example.com) into IP addresses that computers use to locate resources on the internet.

Here you can enter the name servers or IP address to make your domain open your website or let you send emails. In general, you have two name servers that you get while subscribing to a hosting option at Sangkrit.net, and in most plans, it is automatically updated by the system.

In special cases of Dedicated Servers etc, you need to update it on your own or with the help of the online support team. This is called working with the DNS.

How Secondary DNS Works?

This additional set of name servers of secondary DNS keeps your domain’s zone file backed up automatically to that second set of nameservers.

If the first i.e. default set of nameservers goes down, the secondary DNS automatically sends a request to the backups that have a zone file identical to the primary set of nameservers.

  1. Backup & Redundancy: When you set up secondary DNS, you configure another server with a copy of the authoritative DNS records from the primary server. This secondary server essentially acts as a backup.
  2. Load Distribution: Secondary DNS doesn’t just function as a backup; it can also help distribute the DNS query load. When users or devices request DNS information, the load can be shared between the primary and secondary servers, helping to distribute network traffic.
  3. Failover Protection: If the primary DNS server experiences an outage or becomes overwhelmed, the secondary DNS server can still respond to DNS queries, ensuring uninterrupted access to websites and services.
  4. Global Accessibility: Secondary DNS servers can be strategically placed in different geographical locations. This can improve the response time for users in various regions and enhance overall DNS performance.
  5. Zone Transfer: The process of keeping the secondary DNS server up to date with the latest DNS records from the primary server is called a “zone transfer.” This ensures that both servers have consistent and accurate DNS data.
  6. Configuring TTL: Time-to-Live (TTL) values in DNS records determine how long a DNS query result can be cached by other DNS servers. When configuring TTL, consider that changes made to DNS records might take time to propagate across all DNS servers.

Secondary DNS is an essential component for maintaining the high availability and reliability of domain name resolution services. It ensures that even if the primary server faces issues, users can still access websites and online resources without disruption.

How To Use Secondary DNS?

In order to use secondary DNS, you must have Sangkrit.net’s Premium DNS on your domain. To add premium DNS simply visit your domain portfolio on your products page at Sangkrit.net.

Next, select the domain name to open its management and you will see an option to subscribe and enable the Premium DNS. Once you are subscribed to Premium DNS, it will provide you the option to use secondary DNS on your website.

Increase Your Website Security With Domain Name Security Extensions

Leave a comment

Domain Name Security Extensions (DNSSEC) increase your website’s security by authenticating the origin of the DNS data. It is a powerful DNS option that activates another level of security to your domain name and website by adding a digital signature record known as DS to the DNS information.

How to use DNSSEC?

You can use it by upgrading to Premium DNS and then you can enable DNSSEC in your account.

How to upgrade to Premium DNS and use DNSSEC?

  1. Visit your domain portfolio on your products page at Sangkrit.net
  2. Select the domain name and open its management
  3. Select the option to subscribe and add the Premium DNS
  4. You can now enable DNSSEC over your domains

All you need to do is enable DNSSEC and the system will take care of the zone signing process on your behalf. There are no complex options to set like general DNS and self-managed DNSSEC which is used when you are not using Sangkrit.net nameservers.

There are some country code domain names such as .IN .US .DE that doesn’t work with secondary DNS, those users may use the Domain Ownership Protection option with Website Security.
