- This page is about the extension itself. For the Wikimedia Foundation CheckUser policy, see m:CheckUser policy.
CheckUser is an extension that allows a user (with the checkuser
permission) to check which IP addresses are used by a given username and which usernames are used by a given IP, without having to run queries directly against the database by hand.
The extension is running live on all Wikimedia wikis.
Updates will be made according to the needs of Wikimedia Foundation wikis; or where critical vulnerabilities are discovered.

Using MediaWiki-Docker
Follow the steps in MediaWiki-Docker/Extension/CheckUser to install this extension inside a MediaWiki Docker instance.
কনফিগারেশন
This tool copies recent changes data to separate tables, and adds to that when new entries are added.
If $wgPutIPinRC
is set to false
, the copied data will not contain the associated IP address.
However, entries added after installation of this extension will contain the IP address.
After installation of this extension, you can reduce $wgRCMaxAge
to make recentchanges shorter without affecting checkuser.
Use $wgCUDMaxAge
to set how far back checkuser data can go, in seconds.
The CheckUser-specific setting $wgCheckUserCIDRLimit determines the largest range that can be checked in a single check.
Its format is the same as $wgBlockCIDRLimit .
The default limit is /32
for IPv6 checks and /16
for IPv4 checks.
To allow this tool to log successful and failed login attempts as well as logouts, set $wgCheckUserLogLogins
to true
.
If you have bot accounts on your wiki, setting $wgCheckUserLogSuccessfulBotLogins
to false
will skip logging successful login attempts to bot accounts.
মিডিয়াউইকি সংস্করণ: | ≥ 1.43 |
If the extension is installed on a multi-wiki install, then you should set $wgVirtualDomainsMapping for the virtual-checkuser-global
to point to a central database table.
Setting this will ensure that the central index tables are actually on a central DB, and therefore the GlobalBlocking global autoblocks and GUC work.
After doing this, you will need to run update.php
to create the tables on the central wiki.
Granting right to use CheckUser
To grant the right to use Special:CheckUser, Special:Investigate and Special:CheckUserLog, a user with user rights management must go to Special:UserRights and enter the user's name in the box, then select the option "checkuser". Once this is done, the aforementioned special pages will show up in Special:SpecialPages page for that user.
To allow users to access the IP addresses of temporary accounts , they should be granted the checkuser-temporary-account right.
To give sysops all the rights this extension provides, put the following into LocalSettings.php
:
$wgGroupPermissions['sysop']['checkuser'] = true;
$wgGroupPermissions['sysop']['checkuser-log'] = true;
$wgGroupPermissions['sysop']['investigate'] = true;
$wgGroupPermissions['sysop']['checkuser-temporary-account'] = true;
To only allow the adding and removing of the checkuser
permission, use the following instead:
$wgAddGroups['sysop'][] = 'checkuser';
$wgRemoveGroups['sysop'][] = 'checkuser';

Special:CheckUser পরীক্ষক ব্যবহারবিধি
প্রাথমিক ইন্টারফেস
- Special:CheckUser যান।
- In the user field, type in the username (without the
User:
prefix), IP address, or CIDR range.
- IP: any IPv4 or IPv6 address.
- CIDR: you can check a range of IP addresses by appending the CIDR prefix. The CIDR prefix value for IPv4 can be between 16-32 and the value for IPv6 can be between 19-128. The smaller number for both ranges can be changed using the configuration variable $wgCheckUserCIDRLimit. For notation, see Help:Range blocks .
- XFF: you can check a client IP address provided by X-Forwarded-For headers by appending
/xff
(for example,127.0.0.1/xff
).
- XFF: you can check a client IP address provided by X-Forwarded-For headers by appending
- Select the information you want to retrieve.
- আইপি ঠিকানাসমূহ খুঁজুন - returns IP addresses used by a registered user.
- কর্মসমূহ দেখান - returns all edits and logged actions made by users using an IP address or range specified in the target field, or if the target is a user all edits and logged actions by that user.
- ব্যবহারকারী খুঁজুন - returns user accounts that have edited from an IP or range.
- In the "কারণ:" field, type in the reason you are accessing the confidential data.
Try to succinctly summarise the situation (for example, "cross-wiki spam"); this will be logged in a log visible only to users with the checkuser-log
permission.

A typical entry in the CheckUser results for a user summary ("get users") is as follows:
- Example (talk | contribs | block) (Check) (20:11, ১১ অক্টোবর ২০২৪ -- 20:12, ১১ অক্টোবর ২০২৪) [5]
- 127.0.0.37 XFF: 127.0.0.1, 127.0.0.5
- Example user agent
This is formatted to fit a lot of information into a format that can very easily be listed and skimmed, but is difficult to read unless you know what the information provided is. The information is laid out as follows:
- ব্যবহারকারী নাম (ব্যবহারকারী সংযোগ) (time period when they edited from the given IP or range) [number of edits from the IP or range]
- IP address edited from XFF: XFF information provided (can be spoofed)
Each IP/XFF combination used to edit is listed, in order of use.
The last ten user agents (browser, operating system, system language, and versions) for each user for edits made in the IP or range are listed afterwards.
XFF Format
XFF (X-Forwarded-For) headers indicate the series of IP addresses used from the user's computer (first) to the last proxy server. In case of Wikimedia, the last proxy server is one of the Wikimedia proxies (listed under $wgCdnServersNoPurge in the Wikimedia configuration file).
In this example:
aaa.aaa.aaa.aaa XFF: 10.4.46.42, 127.0.0.1, aaa.aaa.aaa.aaa, 208.80.152.46
- the first two addresses (
10.4.46.42
,127.0.0.1
) are private to the originating network and can't be reached directly from the public Internet,
- the third address (
aaa.aaa.aaa.aaa
) is the "public face" of the editor, usually a broadband or dial-up ISP, a company gateway, (but possibly an anonymizer or a malware-compromised server),
- the last address (
208.80.152.46
) is one of the Wikimedia squids (sq36.wikimedia.org
).
MediaWiki configuration settings $wgUsePrivateIPs , $wgCdnServers , $wgCdnServersNoPurge and extensions using the IsTrustedProxy hook (such as Extension:TrustedXFF ) change the way an actual IP address used to attribute edits is selected.
Personal tool links
When you get results from Special:CheckUser you can add personal user tool links via the following interface messages:
MediaWiki:checkuser-userlinks-ip
for IP addresses (for example m:MediaWiki:checkuser-userlinks-ip)
MediaWiki:Checkuser-userlinks
for registered users (for example m:MediaWiki:Checkuser-userlinks)
MediaWiki:checkuser-toollinks
for IPs in the 'Get IP Addresses' check type (for example m:MediaWiki:checkuser-toollinks)MediaWiki:Checkuser-cidr-tool-links
for IP ranges produced by the CIDR calculator present at the bottom of all Special:CheckUser pages. Interface message added in 1.41.
Special:Investigate usage
Basic usage
- Go to Special:Investigate.
- In the ব্যবহারকারী নাম বা আইপি ঠিকানা field, type in up to 10 targets, which may be usernames (without the
User:
prefix), IP addresses, or CIDR ranges. - In the কারণ field, enter the reason you are accessing the confidential data, as described in the Special:CheckUser instructions above; this will be logged in a log visible only to users with the checkuser-log permission.
-
Input form
-
Account information tab
-
IPs and user agents tab
-
Timeline tab
For advanced feature usage, see Help:Special Investigate.
Customizing tool links
As with Special:CheckUser, links to external tools can be customized.
The links are defined in the checkuser-investigate-compare-toollinks
message.
This message is parsed to find links, which are added to the menu in the আইপি ও ব্যবহারকারী এজেন্ট tab.
Showing IPs for temporary accounts
মিডিয়াউইকি সংস্করণ: | ≥ 1.40 |
The CheckUser extension will show since MediaWiki 1.40 a button that is displayed next to temporary account user links which allows the revealing of their IP address.
This functionality is available exclusively to users with the checkuser-temporary-account
privilege, granting them the ability to view the IP addresses that are linked to temporary accounts.
To access this information, the Enable revealing IP addresses for temporary accounts feature must be enabled on the user's Special:Preferences page.
These buttons will appear wherever user links are shown for a temporary account, such as when viewing page histories or in Special:Contributions. However, these will not be shown on Special:CheckUser, Special:Investigate or Special:InvestigateBlock.
APIs
CheckUser and CheckUserLog API
CheckUser provides an API that allows access to the information shown on Special:CheckUser and Special:CheckUserLog.
These two APIs work fairly similarly to the special pages, but the reason for a check using the checkuser
API is prefixed with "API:" to indicate they were made using the API.
Example usages of these APIs are shown below.
- CheckUser API
api.php?action=query&list=checkuser&curequest=userips&cutarget=Jimbo_Wales api.php?action=query&list=checkuser&curequest=edits&cutarget=127.0.0.1/16&xff=1&cureason=Some_check
- CheckUserLog API
api.php?action=query&list=checkuserlog&culuser=WikiSysop&cullimit=25 api.php?action=query&list=checkuserlog&cultarget=127.0.0.1&culfrom=20111015230000
Temporary Account Reveal API
মিডিয়াউইকি সংস্করণ: | ≥ 1.40 |
Usage
The TemporaryAccountHandler class offers API endpoints for retrieving the IP addresses associated with temporary user accounts. To access this information, the Enable revealing IP addresses for temporary accounts feature must be enabled on the user's Special:Preferences page.
API endpoint
GET /rest.php/checkuser/v0/temporaryaccount/{name}
where {name}
is the user name you want to look up
Response
If the request is successful, the API will respond with a JSON object containing the following fields:
Name | Type | Description |
---|---|---|
ips
|
string[]
|
IPs of the given temporary account |
If the request fails, the API will respond with an appropriate error code and message.
Example request
GET /rest.php/checkuser/v0/temporaryaccount/*Unregistered%202
Example response
{"ips": [ "114.127.69.62" , "212.47.235.82" , "212.47.235.81" ]}
TemporaryAccountRevisionHandler
The TemporaryAccountRevisionHandler class offers API endpoints for viewing the IP associated with a revision for temporary accounts. You can specify one or multiple revision IDs in the query string.
API endpoint
GET /rest.php/checkuser/v0/temporaryaccount/*Unregistered%203/revisions/{revisionId}
where {revisionId}
is the revision ID(s) you want to look up separated by the |
character.
Response
If the request is successful, the API will respond with a JSON object containing the following fields:
Name | Type | Description |
---|---|---|
ips
|
dictionary
|
The revision ID as the key and the associated IP address as the value. |
If the request fails, the API will respond with an appropriate error code and message.
Example request
GET /rest.php/checkuser/v0/temporaryaccount/*Unregistered%203/revisions/31
Example response
{"ips":{"31":"40.175.36.227"}}
Example request with multiple revisions
GET /w/rest.php/checkuser/v0/temporaryaccount/*Unregistered%205/revisions/194|193
Example response
