If a Windows Server is running the DNS Server service it will register all the IP addresses bound to the DNS Server service in it's DNS zone(s).

If this is undesired, a registry entry must be added with the IP addresses that should be registered in DNS.

After setting this key a restart of the DNS Server service is required to make the change take effect.

Query the registry key:

"%SYSTEMROOT%\system32\reg.exe" QUERY "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v PublishAddresses

Set the registry key:

"%SYSTEMROOT%\system32\reg.exe" ADD "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v PublishAddresses /t REG_SZ /d "10.0.1.10" /f
