SOLVED: Skype Uses Port 80 For No Reason
May 11th, 2009 | by Troy Larsen | published in Software
I would like to warn everyone who uses Skype: beware of your chat/instant messaging client if you do any kind of web development on your computer, as Skype, for some very obscure reason, uses port 80 (yes, the standard HTTP port) to connect to whatever communication server it has to talk to in order to get you online.
