This template exists to give a quick idea of an IP's background, who owns the IP address and if necessary, a quick way to find or open either a promotion nomination or a problem report.
This template takes one expected parameter: an IP (without the prefix "User:"), for instance {{IPcheck|127.0.0.1}}. If this is not provided, the default will be "127.0.0.1".
This template begins with stable links: user page, talkpage, sock tag link, contribution history, contribution count, WHOIS, RDNS, trace, RBLs, http, logs and block log entry.
This template also displays a list of conditional links to subpages titled with the IP's name: request for arbitration, request for comments on user conduct, long term abuse, request for checkuser, suspected sock puppets, and (only if they exist) the categories for confirmed and/or suspected sock puppets of this user.
If this template cannot find a subpage for the IP address (perhaps because a request has not yet been accepted, e.g. for arbitration), it will form a gray link to the main topic page, trying to find [[PAGENAME#IP Address]] instead. Besides finding entries that may not have subpages, these links may ease creating nominations or reports.
Where several subpages may possibly exist (there could be more than one "arb", "rfc", or "socks"), this template links to a list of subpages for this username.
To make the template also link to this IP's entry on Wikipedia:List of banned users, add the optional parameter ban=y. The "ban" link will appear between the "block log" and "arb" links.
User information templates provide informational links for a user; they are similar to signatures, but often provide additional information, and may be used by other users. List:
