MediaWiki:Checkuser-log-entry-ipusers-xff/qqq

This is an entry in the checkuser log when a checkuser checks which users have used an XFF IP address (XFF means X-Forwarded-For. Some providers use proxies to forward user requests. This effectively means anonymization of requests. To make the requesting user identifiable again, the original requesting IP is transmitted in a separate HTTP header, the XFF header.).

Parameters:
 * $1 - the user who did the check
 * $2 - the IP address
 * $3 - a formatted timestamp of the event

See screenshot "Example log".
