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 $3 edits will be returned for performance reasons.
Use this in accordance with policy.

Type of CheckUser request:
;userips:Get IP address of target user.
;edits:Get changes from target IP address or range.
;ipusers:Get users from target IP address or range.

Add up to $1 {{PLURAL:$1|Username or IP|Usernames or IPs}} and get all the information in one place. Don’t worry, we’ll create a separate CheckUser log for each of them.

Click to see all other users on the IP. You can do this for Users too, and see all the IPs they’ve been using. We’ll automatically create a CheckUser log item for you.
