Similarly, steps 6-8 update the inverse mapping from the IP address to the domain name (type PTR RR).

In the correct setup, the LDNS should point the DHCP client to a domain name server (could be itself) inside the internal network.

The following list illustrates a typical example of how a private DNS update leaks out to the global Internet. The DHCP client first sends a query to its local domain name server (LDNS) and asks for the authoritative server for the zone of its domain name (step 3).

Once the DHCP client receives a response (step 4), it sends the update to the indicated server (step 5).

Both DHCP clients and servers can generate DNS updates.

To turn off DNS updates on Windows 2000/XP/2003 configured with DHCP clients (refer to Figure 1): To turn off DNS updates on Window Server 2000 running DHCP Server (refer to Figure 2 below): Microsoft Windows Server 2003™ automatically sends DNS updates to each of its DHCP clients.

The LDNS thus iteratively sends the SOA request, starting with a root DNS server, and eventually returns the server (step 8).

For Linux or Free BSD systems that use ISC's DHCP client and server software, the dynamic DNS update feature gets set to off by default and requires manual intervention to turn on the service.While you are on this tab, its worth setting the conflict resolution attempts to 3 or 4 which gives DHCP the opportunity to resolve any issues itself.Once you have these credentials set, restart your DHCP server service.Most of you won’t be running Windows 2003 anymore, but if you are, this link may be of interest: DHCP setup primarily is the place to start with this, it is often overlooked that there needs to be a username entered into DHCP to allow for these Dynamic Updates to take place.This user account only needs limited privileges, it must be a member of DNSAdmins, DNSUpdate Proxy, DHCP Users and DHCP Administrators.
