Is it just 1 account per IP????

[Razamon]

So.... I loaded up everything ok on the laptop.... works great..... Started to load up everything on my girlfriends computer and I cant log into EQ now..... Is it the same thing goin on like SWG???? you are assigned an 1 account to IP??? all other accounts made on same IP are banned??? I don't understand... Does anyone have any insight??? I have tried having the new LS account on mine, then I signed her up on her own Account and her own LS account and only 1 of us can be on at a time.... doesn't matter if she uses her own account or one of my LS accounts..... Any answers???
