Hi,

As it stands it looks like someone is accessing an IRC (internet relay chat) server. But since this is incoming traffic, you need to check your self for possible irc bots that may have been deployed on your network.

Secondly, if you are using a Win2K box then port 6667 is used to comunicate with the UPS.

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.
