nslookup response Default Server Unknown, Address ::1

nslookup response Default Server Unknown, Address ::1

When I do a nslookup, I get the response listed below:

C:\Windows\system32>nslookup
Default Server:  UnKnown
Address:  ::1

As far as I can verify, EDNS0 is disabled, PTR records exist for the server in the zone. Also, on the server, if I uncheck the IPv6 protocol in the TCP/IP properties of the NIC, this issue goes away.

Resolution:

Check the IPv6 settings to obtain DNS server address automatically

Change the preferred DNS server from ::1 to obtain DNS server address automatically.
