Are Domain Controllers DNS Servers?

DNS is a system that allows computers to communicate with each other by referring to DNS servers. These servers can provide information about the names and addresses of other computers on the Internet. Domain controllers control DNS.

Domain controller (DC) and DNS are both essential for the proper functioning of a network. However, there are some key differences between the two. Domain controller functions as the primary repository for Active Directory information and acts as the authoritative source for domain name resolution.

A domain controller provides DNS for a domain. A domain controller stores the zones and records for the domain, and provides DNS services for the domain. When a client computer tries to resolve a name in the domain, the client computer contacts the domain controller for the answer.

Ensure DNS is configured on all domain controllers in your Active Directory forest. DNS is required in order to resolve domain name references to IP addresses. If DNS is not configured on a domain controller, Active Directory cannot resolve domain name references.

Hosting vs Domain: Many people mistakenly refer to DNS hosting and domain name services as the same thing. While they share some common features, they are actually two very different services. DNS hosting provides a platform on which you can host a wide variety of websites and applications.

Domain name services (DNS) are a critical part of the internet infrastructure. Domain name servers (DNS) are the servers that handle the requests for domain names and IP addresses. A DNS server can provide information about the name servers that have the appropriate records for a particular domain name.
