How does DHCP integrate with DNS?

What will be an ideal response?

Here's a brief explanation of how DHCP integrates with DNS:
Server addresses (and sometimes their associated services) are advertised using DNS, which resolves domain names into IP addresses, and vice versa.
DNS is not a dynamic environment, so all address updates must be entered manually (either through a GUI interface, on Windows Server 2008, or by editing text files on UNIX systems).
Client addresses usually come into play only when e-mail addresses of the form user@domain.name must be resolved. E-mail servers can resolve this information from MX records associated with the client's domain name (not his or her IP address), so dynamic address resolution works perfectly well for clients and e-mail. Hence, client addresses typically have no impact on DNS, or vice versa, and can change, as needed.
