python socket dns query will get the correct result while the dig will not.

When you ask dig, you are always asking for a DNS lookup. But
gethostbyname does a lot of other things too. My guess is that your
/etc/hosts has an entry for that domain. It's also possible that your
DNS resolver is misconfigured, especially since the authoritative
servers for that domain disagree with your dig results.
