I have noticed that there are three other IP addresses showing up when I review my account activity in settings:
198.228.206.238
501.139.160.16
198.228.195.69
These are not my IP addresses nor anyone in my family with other computers in my home. It appears two are AT&T and another Comcast Cable - all from different locations. Can someone explain how this happens? Have I been hacked or is someone tracking me?
The two 198.x.x.x IPs are wireless IPs probably your cell phone checking your email account. Do you have the Outlook app installed? I wouldn't worry about either of them unless you don't have a cell phone or iPad with a cellular connection.
