IP Address

I have a problem with a memory leak on my W7 running http and mail. In order to isolate the problem I started with CIS only and noticed that thje computer
tried to open a connection to 204.244.102.19 port 80. I tried that manually but it was forbidden. Is that a comodo address?

What process was trying to connect to the 204.244.102.19? The IP address belongs to Westel ISP from Canada.
