Commons:Temporary account IP viewer

This page is a work in progress page, not an article or policy, and may be incomplete and/or unreliable.
Please offer suggestions on the talk page.

This page in a nutshell: The ability to view the IP addresses used by temporary accounts can be granted to non-admins who meet certain criteria. This tool is only for combatting policy violations and each use is logged.

Temporary accounts (formerly called IP Masking) are coming to Commons on 12 November 2025. Admins will automatically see temporary account IP information if they have opted-in through Special:Preferences. Qualified non-admins may request the temporary account IP viewer permission, which allows selective viewing of temporary account IP information.

Access to temporary account IP address information is logged. This log is viewable by checkusers only.

There are currently 4 users with temporary account IP viewer rights, which together with Commons administrators makes for a total of 178 users with this permission.

Criteria for granting

To be eligible for the permission, an editor must:

Make a request for the permission (admins are not permitted to assign the right without a request)^{[Note 1]}
Have a registered account for six months^{[Note 1]}
Have made at least 300 edits to Commons^{[Note 1]}
Have patroller right or license reviewer right in Commons^{[Note 2]}
Agree to use the IP addresses in accordance with Foundation policy, solely for the investigation or prevention of vandalism, abuse, or other violations of Wikimedia Foundation or community policies, and understand the risks and responsibilities associated with this privilege ^{[Note 1]}^{[Note 3]}

Admins are permitted to decline applicants who meet these criteria but are otherwise unsuitable for access to this tool. Stewards are authorized to make exceptions to the Foundation requirements (criteria 1–3 and 5) if someone needs access for a purpose that cannot be reasonably addressed by users who already have this access.

Once the permission is granted, editors must visit their preferences and enable "Preferences → User profile → Enable revealing IP addresses for temporary accounts".

Requests for the permission may be made at Commons:Requests for rights#Temporary account IP viewer.

Criteria for use

Use of the temporary account IP viewer tool must follow the Access to Temporary Account IP Addresses Policy. Use of the tool is logged at Special:Log/checkuser-temporary-account.^{[Note 1]} Editors must be extremely careful with how they publicly discuss conclusions drawn from the temporary account IP viewer tool.

What can and can't be said

Publicly linking a temporary account to another temporary account is allowed.
Publicly linking a temporary account to an IP (including old IP edits) is not allowed unless though behavioral evidence.
Publicly linking a temporary account to a regular account is not allowed unless through behavioral evidence.
Publicly describing temporary accounts in relation to each other (e.g. same ISP, proxy use, geolocation) is allowed, but not in absolute terms (e.g. "they both geolocate to X").
Checkusers will not publicly link regular accounts to temporary accounts (since temporary account IP viewers and admins can see the IP behind a temporary account, this is equivalent to IP information disclosure).

Criteria for revocation

Admins are permitted to remove the temporary account IP viewer permission for the misuse of the right, including the disclosure of temporary account IP addresses in violation of the Access to Temporary Account IP Addresses Policy.

Additionally, the permission will automatically be removed from editors who have been inactive for a year.^{[Note 1]} This process is not yet implemented but announced by the WMF.
