**Feature summary** (what you would like to be able to do and where): Add a link to the /16, /24, /32, etc common CIDR notation subnets from [[Special:IPContributions]], for example:
{F69881651}
(this is done on enwiki with a script [[https://en.wikipedia.org/wiki/User:Daniel_Quinlan/Scripts/RangeHelper.js|User:Daniel_Quinlan/Scripts/RangeHelper.js]] but I feel like having them in core won't be a bad idea)
**Use case(s)** (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
- Admins/TAIV wanting to see disruption across a specific range
- Following TA/IP hopping LTAs
**Benefits** (why should this be implemented?):
- Admins/patrollers being able to make judgments on which range to block
==== Acceptance criteria
* Add a link to the /16, /24 and /32 CIDR notation subnets to the top of Special:IPContributions]
