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.

Premium DNS Improves Your Business Visibility On The Internet

Leave a comment

Every domain name work over the mechanism of DNS called Domain Name System which is also known as Domain Name Server.

By default, you are provided with a set of standard DNS functions that enables you to manage your DNS records and zones but at Sangkrit.net you have an option to upgrade your standard DNS functions to Premium DNS as that offers you more control and flexibility than standard DNS.

Helps You Always Stay Online

Relying on one DNS server creates more chances of a single point of failure. Because when the primary server will go down or fail or is hit by an attack, your visitors no longer get access to your website.

Here, comes the use of secondary nameservers so that it can share the load of incoming domain requests and the primary server doesn’t get overloaded as its failure in processing requests causes denial of the service requested by the client.

You must have noticed that sometimes the web browser takes time to process requests and open a website or shows an error of too many requests or request time out. Secondary DNS saves you from that, it empowers you to back up your DNS zone files using a secondary set of nameservers so that your website never goes offline.

Increases Your Website’s Security

A secured web page is more likely to be shown on search engines, of course, if it has the quality content the user expects.

Premium DNS offers you DNSSEC that increases your online security by authenticating the origin of DNS data. It makes the resolver cryptographically verify the data received is actually coming from the zone where it originated.

It also helps the resolves to know that the data hasn’t been modified in transit and is signed by the zone owner with private keys.

Lets You Update SOA Records

Apart from this it also enables you to update SOA i.e. the Start of Authority records which has zone caching information. The zone has the administrator’s email address and the primary nameserver for the zone. It also holds incrementing numbers which, when updated, trigger the DNS to reload the zone data. You can request to have these numbers updated.

Have More Zone Records Per Domain

It also allows you to increase the number of zone records, you can manage your zone file with 1500 DNS records per domain to give you more control, redundancy, and better performance.

You can upgrade anytime from standard DNS to Premium DNS right from your Sangkrit.net account by accessing your Domain Settings and choosing the option to add Premium DNS.
