Unable to Perform Zone Transfer: The DNS query name does not exist: localhost about octodns-bind

Interesting.

If you do this below and see if it resolves.

>>> import dns.resolver
>>> dns.resolver.resolve('localhost')[0].address
'127.0.0.1'

Fix over in #25

Oh this probably happens because dns.resolver does actually query a resolver immediately and doesn't go through the normal chain of things (host file, etc.) before making it. So in some cases you have like systemd-resolved dealing with that or whatever resolver may be running locally on the machine and then going to a real resolver, but if your resolver is 1.1.1.1 or something and it queries it, you won't get anything.

Interesting, may need to change that so it does the actual looking into host file, etc or just handle the localhost -> 127.0.0.1 in the code (which I don't love). Probably need to use socket.gethostbyname
