Hi,

Perusing my logs, my query-log (BIND 8.3.4, FreeBSD 4.7R) is suddenly filled
with odd queries for "extra". Like so:

.... XX /207.217.120.20/extra.asarian-host.net/MX/IN

No "extra" exists, btw. It seems some for of attack. Many of these queries
also come from legitimate name servers, so I cannot just block them all.

Has anyone ever seen this before? Do I need to be worried? And what can I
do?

Thanks!

- Mark
