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

Over 97% of DNS updates that leak onto the global Internet come from Microsoft Windows™ operating systems (see companion paper on The Windows of Private DNS Updates).

By default, the ACL gives Create permission to all members of the Authenticated User group, the group of all authenticated computers and users in an Active Directory forest.

However, in many cases when the DHCP and DNS configurations have inconsistencies, the LDNS may direct the DHCP client to a place outside the local scope, resulting in leakage of private DNS updates to the global network.

In the example shown above, the LDNS is not configured with a local zone for 168.192.

The system is also reachable from outside its domain.

The DHCP service can use DNS in two ways: You can enable the DHCP service to update the DNS service for DHCP clients that supply their own host names.

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.Microsoft Windows operating systems support a feature that dynamically updates the mappings of domain names to associated IP addresses assigned to hosts by DHCP servers.This automatic updating, called Dynamic DNS Updates service, reduces the administrative overhead associated with manually administering DNS records of network hosts.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.While this service can reduce administrative overhead, it also can, and does, have deleterious effects on the larger Internet by leaking traffic regarding private IP addresses that should never leave the local area network.
