The only time BIND changes the SOA serial number by itself is when the
server implements dynamic update. Since this wasn't implemented until
BIND 8, I don't understand what this thread is talking about. BIND 4
never had any reason to bump the serial number by itself, it's something
that the DNS administrator always had to do after he edited the zone
file. And he should do it even if the only change he's made is to the
other fields of the SOA record -- otherwise, those changes won't
propagate to the slaves.
