Sorry, I misread your post. I thought you were
referring to a regular
IP block. Since the IP was blocked as an open proxy, please let the
blocking admin (and other admins) know that the IP is not an open
proxy, but is a shared IP belonging to a school. Once, my school IP
was blocked as an open proxy (it was not an anon-only block), but I
managed to get the admins to make the block anon-only. Hopefully,
after you have notified the blocking admin, they will change the block
to an anon-only block.
Sometimes shared IPs are reported as open proxies when they have an open
proxy on the network behind them. The appropriate solution is to have the
shared IP send X-Forwarded-For headers so that we can tell the normal
requests from the open proxy requests.
