Since this one doesn't seem to be the first time, please consider the
Use descriptive topic titles phrase, as mentioned n the
AlliedModders Rules:
With thread titles like "help plugin", or "can you help me", - you can be very sure that the majority of all people will just ignore your threads.
Based on your phrasings / thread content, I have edited your title to "
Restricting features by IP or MAC address", if you don't feel that one is fully appropriate for your thread, you can click Edit Post, then go to Advanced Mode to make further adjustments to the title.
All that being said, SourceMod already allows you to provide access privileges based on IP address, see
Adding Admins (SourceMod) for more information.
A caveat there may however be that if your "provider" for example have 1024 IPv4 addresses, then you must add each one of them individually, meaning 1024 lines.
