Question

Need help with this tutorial: www.digitalocean.com/community/tutorials/how-to-configure-bind-as-a-private-network-dns-server-on-ubuntu-14-04

When I do nslookup app2 (or app1, ns1, ns2 depnding on which droplet i am on) I always get the external IP address of my ns1 - any ideas where I have gone wrong? Anything in italics are just placeholder values.

Server: 8.8.8.8 Address: 8.8.8.8#53

Non-authoritative answer: app2.lon1.domain.com canonical name = domain.com. Name: domain.com Address: 436.202.70.342

Are you wanting to get the localhost settings for the DNS query?

If so, try dig app2 @localhost

This seems to indicate that the domain’s zone includes a CNAME record that is causing this response. Can you share the zone file you are using for your domain so we can identify the issue?

A CNAME will direct any requests for the specified name to the ip address associated with the second name so if app2.lon1.domain.com is CNAME’ed to domain.com the A record for domain.com is used to determine the IP.
