DNS is the core of the internet, which turns domain names into IP addresses. The fundamental aspect of DNS is the capability to add NameServer or NS records for a subdomain.
The process of setting up a nameserver for a subdomain is an important step in simplifying your domain’s DNS configurations. Irrespective of whether you’re allotting a subdomain for a particular service, like a blog, online store, or for business purposes, correctly setting up a nameserver is necessary.
In this article, we’ll help you understand how to add an NS record for a subdomain so that you can effectively manage your online presence.
Adding an NS Record for a Subdomain
To use different name servers for a subdomain, you will need to follow these steps:
1. Create the Subdomain
In your domain registrar or DNS management interface, create the subdomain you wish to use. For instance, assume that your main domain is xyz.com and you wish to create a subdomain, named sub.xyz.com, then create it.
2. Set Up Delegation
In order to employ different NS records for your subdomain, you’re required to delegate DNS management for that particular subdomain to the new name servers. It is done by adding Name Server (NS) records for the particular subdomain in the DNS settings of your main domain.
- Look for the DNS settings for your main domain (xyz.com)
- Add NS records for the subdomain (sub.xyz.com). Ensure that the NS records are pointing toward the name servers that you wish to use
For example
- sub.xyz.com. IN NS ns1.otherdns.com
- sub.xyz.com. IN NS ns2.otherdns.com
3. Configure the New Name Servers
Configure the DNS records for the subdomain on the delegated name servers. This includes A records, CNAME records, MX records, etc., as needed for your subdomain.
4. Propagation
Once you make these changes, it usually takes up to 48 hours for the DNS changes to propagate throughout the internet.
Example Scenario
1. Main Domain Setup
– Domain: xyz.com
– NS records for xyz.com might be:
- xyz.com. IN NS ns1.maindns.com
- xyz.com. IN NS ns2.maindns.com
2. Subdomain Delegation
– Add NS records for sub.xyz.com:
- sub.xyz.com. IN NS ns1.otherdns.com
- sub.xyz.com. IN NS ns2.otherdns.com
3. Subdomain DNS Setup
– On ns1.otherdns.com and ns2.otherdns.com, configure DNS records for sub.xyz.com as needed (e.g., A record pointing to an IP address).
Important Considerations
- TTL (Time-to-Live) Setup: Customize Time-to-Live (TTL) configurations as per your requirements for faster updates or caching.
- Domain Registrar: Some registrars may have specific interfaces or requirements for setting up NS records, so consult their documentation.
- Testing: Use tools like dig or online DNS lookup tools to verify that the delegation is set up correctly and that the subdomain resolves as expected.
Using these steps, you can effortlessly handle a subdomain with the help of multiple name servers from the main domain.
Configuring an NS record for a subdomain is a simple and easy process that improves domain management and system functionality. By properly setting up the nameservers, you can make sure that your subdomain works efficiently, offering a more customized and satisfying user experience. If you’re handling several subdomains or want to streamline your domain configuration, knowing this process is important to maintain a strong and well-coordinated online presence.
