DNS (Domain Name System) is a hierarchical database of the top level domains (TLDs) and the second level domains (SLDs) registered with the Internet Assigned Numbers Authority (IANA).
DNS is used for resolving hostnames to IP addresses. When a user types in a URL, their computer queries DNS for the IP address associated with that URL.
If DNS can’t find the IP address in its database, the computer asks the Local Host (also known as the DNS Server) for the IP address.
Domain controllers use DNS to store the DNS data for their domain. This data includes the top level domain and second level domain for all the domains in the domain controller’s forest.
The domain controller uses this data to answer DNS queries.
A domain controller can also use DNS to update the data in its database. For example, if a company changes the name of its domain, the domain controller updates its DNS data to reflect the new name.

Domain controller DNS (DC DNS) is a feature of Microsoft Windows Server 2003 and later that allows a DNS server on a domain controller to act as a primary DNS server for the domain. The domain controller can also provide secondary DNS services for other DNS servers in the domain. When a user attempts to resolve a name using a DNS server outside the domain, the domain controller can use its database of domain records to provide the answer.
When setting up a new domain, it is important to set the DNS servers to the correct values. The Domain Name System (DNS) is the system that translates human-readable domain names like “contoso.com” into the corresponding IP addresses. The default setting for DNS servers on domain controllers is typically to use the IP addresses of the local network.
Domain name system (DNS) is a hierarchical naming system for computers, phones, and other devices. DNS loads webpages and other documents from a central server, rather than from the individual devices. A domain name is a unique name assigned to a particular organization or company.
One of the most important decisions you will make when setting up your domain is which Domain Name System (DNS) to use. There are many different types of DNS servers, and each has its own advantages and disadvantages. The following is a breakdown of the different types of DNS servers, and their respective advantages and disadvantages.
