I found out recently because of a netnanny program that I installed, that this ip-18.104.22.168:443-is repeatedly trying to connect to my comp. I have tried looking it up, but am getting that it is an invalid ip. Any ideas?
The IP is 22.214.171.124 without the :443. 443 indicates the port and is a secure connection which may be related to netnanny.
A TCP/IP communication has two basic destinations when the communication happens. One is the address, the other is a port. Have you noticed how some HD channels have sub-channels? Sort of the same idea here.
When communications are looking for a particular application, they talk on a certain port. And TCP/IP notation puts that port after a colon. So 126.96.36.199:443 is IP address 188.8.131.52 and destination port 443. And 184.108.40.206 belongs to Akamai.
They provide a ton of hosted services for things like Microsoft Update, Adobe, stuff like that. Odds are, you've got something that is supposed to receive regular software updates. It COULD be something bad, but Akamai is well-known, and is probably fine.
