MediaWiki:Checkuser-summary-limited
From Test Wiki
This tool scans recent changes to retrieve the IP addresses used by a user or show the edit/user data for an IP address. Users and edits by a client IP address can be retrieved via XFF headers by appending the IP address with "/xff". IPv4 and IPv6 are supported, but your account is not able to check IP ranges. No more than 5,000 edits will be returned for performance reasons.
For privacy reasons, you are only able to check your own username or IP address for testing purposes. If you need a CheckUser performed for a reason other than testing, please contact a steward or sysadmin.
Stewards, you can perform checks on other people by adding the Checkuser right to your account.
Your current username is "$1" and your IP address is "$2".
