I am the it admin from a school and we are encounter the error of too many sessions from 1 ip

hi, i am the it admin from a school in the Netherlands. We would like to use more chatgpt in our lessons, but we encounter the error of too many sessions from 1 ip. our students go to chatgpt on their own account, but through the school network and thereby use one of our 3 connections. is there a way to get these addresses white listed?

I already saw the question come by multiple times and didn’t see a real answer. There is no way to contact anybody from support directly, so i have to try it this way.
