Host should not look at your /etc/hosts file. It's one line description

host - query nameserver about domain names and zones

Mine looks like this for my machine with one interface:
127.0.0.1 localhost
192.168.0.3 sandworm.lowerplanes sandworm
For my gateway with a "static" DHCP assigned address (sterilized to
prevent spam/script kiddies trawling it anymore than they already do)
and a second card for the internal network:
127.0.0.1 localhost
192.168.0.1 richese richese.lowerplanes
24.10.xxx.xxx cbxxx-a cbxxx-a.rchstr1.mn.home.com

Right.

and similar functions.
I'd have to scour the source of host to see if this is the expected
behavior. I think the program should query nameservers directly since
that is it's intended purpose.

How many interfaces does this machine have? Is it a gateway system for
the other machines in the network? If so, do they have your
"myhostname" in /etc/hosts or does your local DNS have the correct
forward and reverse information for your "myhostname." I run my own
internal DNS for my bogus domain lowerplanes.

I don't think so but I could be wrong.
