You do not need to disable dynamic DNS updates if: However, if you have configured your host to act as a DHCP client/server and you make use of the private IP address space (including 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16) specified in RFC1918, you should turn off the dynamic DNS update feature.
Most home users who use DSL/Cable routers as DHCP/NAT servers to facilitate multiple host connections to the Internet should turn off dynamic DNS updates.
``So what if my host leaks a few packets to the global Internet? '' The reason is that inconsistent configuration between your home hosts and your local DNS servers can, and often does, cause leakage of DNS updates for private IP addresses to the global Internet.
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.
Microsoft Dynamic DNS (DDNS) is a wonderful feature.
In the example shown above, the LDNS is not configured with a local zone for 168.192.
The LDNS thus iteratively sends the SOA request, starting with a root DNS server, and eventually returns the server (step 8).
Once the DHCP client receives a response (step 4), it sends the update to the indicated server (step 5).
Similarly, steps 6-8 update the inverse mapping from the IP address to the domain name (type PTR RR).
Leakage of private DNS updates is caused by inconsistent configuration between DNS servers and DHCP client/server entities.
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).
