Question about IP Exemptions

[tekniq]

Does this work per single IP or any IP? I don't want to get unintentionally banned...

For Example:

I recently got my roommate to play EQ (teaching a new player from scratch how to play a 50+ account is a pain, but back to topic).

We have an IP exemption at our apartment, but will this still apply if we're both traveling on a business trip or when he comes over my hometown house for an EQ lan party?

Thanks in advance.
