Since upgrading a test server to 9.3.0, I have begun seeing the following
messages logged on my server that involve the same host.
general.log:12-Oct-2004 09:08:24.031 general: info: zone

The host 128.244.47.217 is a DNS also running BIND but it is configured to
perform its zone transfers from other servers. I reviewed the named.conf
for this server and saw no references to my test server at all. Thus, I'm a
little confused as to why this host is attempting to send notifies to my
server when my test server is not configured as its master. It's only an
informational message so it's obviously not too serious but I would still
like to get a better understanding of exactly what is going on here and if
there is anything I can do to stop the logging of these messages.

Thanks,
