Today i was looking through logs on my small home network and notice this:

8/20/2003 00:52:13:721 Outbound TCP 60104 145.40.55.234 11.242.122.141 23168

Doesn't look out of the ordinary, execpt all ips on my network are static and all are in the 192.168.*.* ip range!
So I do a whois on 11.242.122.141 and guess who it is, Department of Defense - Network Information Center - Science Applications Center!

Should i be worried about this?
