Probably from home network computer.

You can take the numbers and go to dnsstuff.com.

Put the numbers in there for an IP look up.

The actual IP address in question would help, although in most cases, incoming traffic like that is often routine. It would help to know whether it's from your home network, your ISP, or outside of your ISP.
it means that either someone's broke into your computer, or a virus is trying to get in, or both. be sure your windows or norton firewall is turned on. try to get the ip address of the hacker, do a virus scan immediately and delete the virus. be sure your anti-virus is turned on at all times and kept up to date. or it could be spyware trying to get in. run a anti-spy scan, and delete anything and everything detected. keep your anti-spy turned on and up-to-date at all times
My McAfee program has a "tracing" feature...does yours?
