Yes, I have seen this IP in our logs since Feb 2 also.  I don't have
any packet captures, only ipfilters and iptables log messages, though.
The source port for all was 6667 and the destination ports were either
1024 or 3072.  It's been logged on at least 10 of my machines, the latest
being about 4am EST today.
