1 account per IP question

[Cadenzia]

Good day,
I know this is an important rule to prevent bots and all.
But I had a question.
Where do I go to contact the owner in order to ask them to allow only two accounts for my specific IP address?
Me and my Parent wish to play EQ together but we are incapable of doing so because of this limit.
If something can be done to change this I would dearly appreciate it. :3

Thank you! <3
