BIND9: dig <hostname> doesn't work, dig <hostname.domain.tld> does.
I just setup a bind9 server. When I dig a hostname without a domain attached, I get no answer in response. When I dig hostname.domain.tld, I do get the correct response. nslookup, host, ping, etc. all work fine. But, they use resolv.conf. I think something is misconfigured with my zone files.
