Hi all,

I have been seeing a lot of strange traffic hitting my firewall and
cannot get a definite as to what it actually is.

>From what I am seeing, it is from the same ip and src port - 6667 but
going to different ip and dest ports.  I have seen this activity from
numerous hosts and a dig cannot find anything about them.

I have seen an massive increase of this traffic over the last couple of
days and can't find any conclusive evidence that it may be a virus in
the wild.  Has anyone else seen this type of traffic?

Any information is greatly appreciated.
Jenn
