Why is my own IP address trying to access my OWN computer?

This seems a little crazy, but when I looked at the history log, it says that

 

"Unused port has blocked communications, Inbound TCP connection from [my IP addess], local service port"

 

This has occured many times in the past few days. My history log has been spammed with that above message. I don't get it, my OWN IP addess is trying to gain access my OWN computer??


What's going on here?
