Question

How can I find the origins of conflicting DNS records?

Answer 1

You could find out the nameservers for a domain with the "host" command:

[davidp@supernova:~]$ host -t ns stackoverflow.com
stackoverflow.com name server ns51.domaincontrol.com.
stackoverflow.com name server ns52.domaincontrol.com.
