How does DHCP update DNS?

Is DHCP the same as Dynamic DNS?

DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System) both work across the client-server architecture though they are different terms. While DNS maps the name of the domain to the IP address, DHCP is a protocol that assigns the IP address to the host in a network either dynamically or statically.

The short answer is that yes you can run all three roles (Active Directory Domain Services, DNS and DHCP) on the same server without any problems.

Why is my DNS not updating?
