I’m seeing many logins to my Stack Exchange OpenID account from the private IP addresses 10.7.2.16 and 10.8.2.15. Another of my accounts says that it was logged in from 10.80.0.144. I was under the impression that accessing webpages via the Internet requires a public IP address.
So, can Internet logins occur from the private IPv4 address range (10.x.x.x)? More specifically, I’m curious if this suggests unauthorized login attempts via the Internet or something else, such as internal logins from the relevant servers.
