BIND does not read the /etc/hosts file.
Underscores have been illegal in host names for a very long time. BIND
8.2 started to enforce that. If you must have underscores in a domain
name, and with the understanding that it's possible that some other
name server may reject that name, then BIND 8 has an option to allow
it. You may use the "check-names" option to turn checking down or off
for a single zone or for the whole server.
However, I strongly recommend that you write a little script to go out
and find underscores in host names and change them. The dash ('-') is
legal.
