Getting locked out from logging in from different IP's?

[Caraway]

Uh oh. Today I logged in to this Forum for the very first time from work and my home IP is different. Does it mean there is a chance my account is suspended when I come home or would it only matter if I would have tried to login to the Game itself using different IP's?

You should be fine. And even if it does get locked out you will receive an email requesting you take a couple of steps to restore your service (primarily changing your password).
