How Do I Delegate My DNS Server?


Angela Bailey

Delegating your DNS server is an important step in managing your domain’s DNS records effectively. By delegating your DNS server, you can distribute the responsibility of managing specific DNS zones to different servers or service providers. This can be particularly useful if you have multiple subdomains or if you want to use a specialized DNS service for certain records.

What is DNS Delegation?

DNS delegation involves assigning authority for a particular domain or subdomain to a separate set of name servers. These name servers are responsible for resolving DNS queries related to that specific domain or subdomain. By delegating, you essentially create a hierarchy of authoritative name servers, each responsible for a different part of your domain’s namespace.

Why Delegate Your DNS Server?

Flexibility: Delegating allows you to have more control and flexibility over your domain’s DNS management. You can choose different providers or servers based on your specific needs.

Improved Performance: By distributing the workload across multiple name servers, you can improve the performance and response time of your DNS queries.

Better Security: Delegating your DNS server allows you to implement additional security measures, such as using separate providers for authoritative and recursive resolvers.

Easier Management: If you have multiple subdomains or complex DNS requirements, delegating can make it easier to manage and organize your records.

How to Delegate Your DNS Server?

To delegate your DNS server, follow these steps:

Step 1: Choose a Name Server

The first step is to choose the name server where you want to delegate authority for a specific domain or subdomain. This can be an external service provider, an internal server, or even another organization’s name server.

Step 2: Configure the Parent Zone

Once you have chosen a name server, you need to configure the parent zone. The parent zone is the main domain that will delegate authority to your chosen name server. To do this, you need to add a delegation record (NS record) in the parent zone’s DNS configuration.


  • In your parent zone’s DNS configuration, add an NS record for your subdomain:
    • IN NS ns1.yournameserver.

Step 3: Configure the Name Server

Next, you need to configure the name server that you have chosen for delegation. This involves setting up the proper DNS records for your subdomain on that name server.


  • Create a new DNS zone on your chosen name server for your subdomain.
  • Add the necessary DNS records (A, CNAME, MX, etc.) for your subdomain.

Step 4: Verify and Test

After configuring both the parent zone and the delegated name server, it’s important to verify and test that everything is working correctly. You can use online DNS lookup tools or command-line tools like dig or nslookup to check if the delegation is set up properly.


DNS delegation offers a powerful way to manage and distribute the responsibility of DNS resolution for different parts of your domain. By following these steps, you can easily delegate your DNS server and take advantage of the flexibility, performance improvements, and easier management it provides.
