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 (CIDR $1-32) and IPv6 (CIDR $2-128) are supported.
No more than 5,000 edits will be returned for performance reasons.
Use this in accordance with policy.
