5.6. Dynamic DNS

Dynamic DNS (DDNS) enables a Windows Server 2008 DNS server to automatically update resource records for clients if their host names or IP addresses change. Host name changes can occur when the remote computer changes computer name or becomes a member of another domain (which implicitly changes its FQDN). The use of DHCP is another argument for DDNS. As DHCP leases expire, a client computer's address can, and is likely to, change. This makes maintaining accurate DNS records for hosts on the network that use DHCP for address allocation difficult. DDNS resolves the problem.

DDNS functions through a client-server mechanism. Windows 2000, 2003, and XP DHCP clients support DDNS and can directly request that a Windows Server 2008 DNS server update their host resource (A) records whenever the clients' IP addresses or host names change. Windows Server 2008 DHCP servers can also submit requests on behalf of clients, although a DHCP server can request an update to both the clients' host and pointer (PTR) records.
