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:
- Visit your Domain Portfolio
- Tap on your domain name
- Select Manage DNS
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
