A Question on IP Exemptions

[Logansrun]

I recently applied for and was approved for an IP exemption for myself and my son. One of my friends has stated playing on the server and may soon be playing on my IP. When I initially applied for the exemption, I did not include his account name in the request. Do I need to make a new IP Exemption and include his login name or will he be able to play with no problems?
