This page in a nutshell:
The global IP block exemption is a global group that allows users to bypass global IP blocks and rangeblocks. Users may request access to
global-ipblock-exempt at Steward requests/Global permissions. If the IP is also blocked locally, users may also request access via UTRS or stewardswikimedia.org.
This group allows the user to bypass global IP blocks, global rangeblocks and Tor exit node blocks, according to the policy at No open proxies#Exceptions.
Users in this group are also allowed to bypass the IP restrictions issued by the StopForumSpam extension.
This group does not affect local IP blocks and local rangeblocks; for which a local IP block exemption is needed.
See this guidance on how to request global IP block exemption.
