Port #'s for blocking update servers topic

Finally gained access to my isp's router to add urls for blocking updates to the AFTV. The router is asking for port #s too, not just urls.

By default it puts in 80. When I tried to access those urls the two notification urls seem to be blocked, but the critical one
amzdigitaldownloads.edgesuite.net is responding when I tested it. Giving me a too busy to answer message.

I am assuming that it is not actually blocked. Does anyone know what the port # is?
