Many administrators are removing DNS delegation when demoting domain controllers. However, this may not be the best practice.
When a domain controller is demoted, it no longer has the authority to resolve DNS names. If the domain controller is the sole source of DNS resolution for a particular namespace, then its delegation may need to be removed in order to avoid service disruptions.
However, if the domain controller’s delegation is only for a subset of the namespace, then it may be better to leave the delegation in place.
A better practice would be to have a secondary domain controller that is responsible for resolving DNS names for the namespace. This secondary domain controller can be promoted to the role of domain controller when the primary domain controller is demoted.

How to Remove Old Domain Controllers from DNS
If your organization has retired an aging domain controller, it’s important to remove the server from the DNS namespace. This process removes the old server from the DNS database, and replaces it with a new server. To remove the old domain controller from the DNS namespace, perform the following steps:
1.
Domain controllers are important servers in a network. They act as the authoritative source for domain name information. When a domain controller is replaced, it is important to remove the old domain controller’s DNS records so that the new domain controller can take over.
If you have an older DNS server that is no longer meeting the needs of your network, you may want to consider removing it. There are a few different ways to go about this, but the most common approach is to use a DNS management tool. One of the most popular DNS management tools is DNS Manager from Microsoft.
Domain Controllers should use themselves for DNS. There are several reasons why this is the best practice. First, it is a best practice to have a single point of administration for your DNS.
Domain controllers are the backbone of a Windows network. They are the servers on which Active Directory (AD) and other critical directory services are run. DNS is an essential part of AD, and it is important that domain controllers have a good DNS implementation.
There has been much debate recently as to whether or not a Domain Controller (DC) should point itself to the DNS servers for the domain. This debate is based on the theory that if a DC is not authoritative for the domain, then users may not be able to access resources on the domain. However, there are also many other reasons why a DC might point itself to the DNS servers.
Domain controllers are servers that act as the primary control point for a domain, and are responsible for ensuring that all DNS requests are handled correctly. By running DNS on a domain controller, you can ensure that all requests are handled correctly and that your domain is fully operational. However, there are a few drawbacks to running DNS on a domain controller.
