Extension:GlobalBlocking/en

The GlobalBlocking extension allows a user with the appropriate permissions to block an IP address or IP address range (but not accounts) on all wikis in a group sharing the same  database. It is intended to be used for combating severe cross-wiki vandalism and spam.

Configuration

 * $wgApplyGlobalBlocks
 * Whether to respect global blocks on this wiki. This is used so that global blocks can be set on one wiki, but not actually applied there (i.e. so people can contest them on that wiki).


 * $wgGlobalBlockingBlockXFF
 * The flag, set to   by default, causes blocks to apply to all of the IP addresses in the X-Forwarded-For (XFF) header. Set this flag to false to disable this feature. For more details, see.

API
Two API modules are provided, one to (un)block users, and another to view existing global blocks. They are documented at Extension:GlobalBlocking/API.

Usage
The following requires appropriate permissions, assigned by default to stewards, which by default can be added or removed by bureaucrats. To make a global block:

To remove a global block:
 * 1) Go to Special:GlobalBlock.
 * 2) Enter the IPv4 address or range (up to /16) that you wish to block (or any IPv6 address or range up to /4 if you made the schema changes prescribed in the installation instructions section of this page or you have the latest revision), and decide if you want to only block anonymous users. To only block anonymous users, check the checkbox.
 * 3) Submit the form. The IP address or range is now globally blocked on your wikis that opt in to the global blocking. Account creation is blocked (even if you selected "anonymous users only": T42190), and the blocked IP or range cannot edit any associated user talk pages on any wiki affected and opted in to the global block. If  is installed, globally blocked IP addresses are prohibited from viewing the abuse log if the particular wiki is opted in to the block.
 * 1) Go to Special:GlobalUnblock and click "Remove a global block".
 * 2) Enter the IP address or range to unblock and the reason, and submit the form. The IP address or range will no longer be globally blocked.
