Formularz wyszukiwania

1. Otwórz Special:CheckUser.
2. Wpisz nazwę użytkownika (bez przedrostka User:), adres IP, lib zakres CIDR w pole Nazwy użytkownika i adresy IP:.
   • To pole przyjmuje dowolne adresy IPv4 oraz IPv6
   • CIDR - możesz sprawdzić zakres adresów IP podając prefiks CIDR. The CIDR prefix value by default is between 16-32 for IPv4 and 19-128 for IPv6. Po dokładny opis zapisu, zobacz Help:Blokowanie zakresów IP .
   • XFF - możesz też sprawdzać adres IP klienta podawany w nagłówku X-Forwarded-For poprzez dopisanie /xff (na przykład, 127.0.0.1/xff).
3. Wybierz informacje, które chcesz uzyskać:
   • Znajdź adresy IP - zwraca adresy IP wykorzystywane przez zarejestrowanego użytkownika.
   • Pozyskaj działania - zwraca wszystkie edycje i czynności dokonane przez użytkowników korzystających z podanego w polu celu adresu IP lub zakresu, albo gdy celem jest użytkownik, edycje i czynności dokonane przez podanego użytkownika.
   • Znajdź użytkowników - zwraca listę kont użytkowników, którzy edytowali z tego IP lub zakresu.
4. W polu Powód podaj powód dokonania sprawdzenia. Lepszy jest krótki opis, ale zawierający wystarczająco kontekstu, by móc kontrolować dokonane sprawdzenia. Zostanie on zapisany w rejestrze widocznym tylko dla użytkowników z uprawnieniem checkuser-log.

Zwracane informacje

Znajdź adresy IP

The Znajdź adresy IP results returns the last IP addresses used by a given user account. An example check is shown on the right in the screenshot.

The format of the results is designed to the results list compact and easy to skim over. The information is laid out as follows:

• 172.18.0.1 (zablokuj) (18:50, 4 maj 2025 -- 21:53, 4 maj 2025) [8] (~8 od wszystkich użytkowników)

WHOIS/RDNS • Sprawdź ten zakres • Poprzednie sprawdzenia tego zakresu

• IP address (user links for the IP address) (time period when they used the IP) [number of actions performed by this user on the IP] (The number actions performed by all users on the IP)

Tools defined in MediaWiki:Checkuser-cidr-tool-links

Pozyskaj działania

The Pozyskaj działania results returns a list of actions performed by all users on the given IP address or range, or if the target is a user all edits and logged actions by that user. An example result is shown to the right in the screenshot.

Actions shown in these results includes any action sent to Special:RecentChanges , but also additionally includes log events only shown in Special:CheckUser such as logging in and logging out of an account.

Znajdź użytkowników

The Znajdź użytkowników results returns the last user accounts that used a given IP address. An example result is shown to the right in the screenshot.

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:

username (user links) (time period when they edited from the given IP or range) [number of edits from the IP or range]
(the user groups this user belongs to)

• IP address edited from XFF: XFF information provided (can be spoofed)
• User agent string
• User agent client hints

Each IP/XFF combination used to edit is listed, in order of use.

After the IP addresses, the last ten user agents (browser, operating system, system language, and versions) and last ten used user agent client hints (since MW 1.41) are shown.

XFF (X-Forwarded-For) headers indicate the series of IP addresses used from the user's computer (first) to the last proxy server. The XFF header is assumed untrustworthy as it can be set to a fake value by the user's computer. The XFF header is considered trusted if all IP addresses are trusted proxies, which causes the XFF to have a green background.

• 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 Znajdź adresy IP 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. (wprowadzono w 1.41)

Wprowadzenie

Special:Investigate is an alternative interface used to lookup CheckUser data for accounts and anonymous users. The tool uses a single-page design which helps avoid opening too many tabs when running checks. However, it lacks several features present in Special:CheckUser such as the display of Client Hints data. The tool can only be used by users with the investigate right. The data shown in the tool has an expiry which is set by default to 90 days.

1. Open Special:Investigate.
2. In the Nazwy użytkownika i adresy IP: field, type in up to 10 targets, which may be usernames (without the User: prefix), IP addresses, or CIDR ranges.
3. In the Powód field, enter the reason for the check. A shorter reason is generally better but you should still include enough context for auditing of checks. This will be logged in a log visible only to users with the checkuser-log permission.

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 IP i aplikacje klientów tab.

Special:InvestigateBlock is interface used mass block users and IP addresses after a CheckUser check. The tool allows you to block multiple targets with the same reason and also add content to their talk page / user page. The tool can only be used by users with the checkuser and block rights.

1. Open Special:InvestigateBlock.
2. In the Nazwy użytkownika i adresy IP field, enter targets to block (which can be usernames, IP addresses, or CIDR ranges).
3. Fill out the block details, including whether you want to add content to their user pages and/or user talk pages.
4. Submit the blocks.

The tool will prevent the user from blocking usernames and IP addresses in the same use of the form to avoid accidentally publicly exposing CheckUser data. Pre-filled links from Special:Investigate and Special:CheckUser are configured so that there are two links where one contains the accounts and the other contains the IP addresses, so that the user will not see this warning when using the form.

This page is used to find all the edits performed by temporary accounts on a given IP address or CIDR range within the CheckUser data retention period (by default 90 days). This page is only available if temporary accounts are known on a wiki.

1. Open Special:IPContributions.
2. In the Adres bądź zakres adresów IP: field, input an IP (IPv4 or IPv6) or CIDR range.
3. Adjust parameters as necessary and submit a search. This action will be logged to the checkuser-temporary-account log which will be visible to users with the checkuser-temporary-account-log right.

This special page is only available if the Extension:GlobalPreferences and Extension:CentralAuth extensions are installed. The tool allows users to see edits performed by a given target across all wikis performed within the CheckUser data retention period (by default 90 days).

The tool can search for the following types of targets:

• A username (named or temporary). This shows the recent revisions across all wikis from that user.
• An IP address or CIDR range. This shows recent revisions performed by temporary accounts on that IP address or range. The user can only see results on wikis where they have the ability to reveal the IP addresses of temporary accounts (as described in the Showing IPs for temporary accounts section).

The page does not show contributions from anonymous users whose name is their IP address. This is due to technical limitations with the current database table structure.

1. Open Special:GlobalContributions.
2. In the Nazwa użytkownika, adres IP bądź zakres adresów IP: field, input a user name, an IP (IPv4 or IPv6) or CIDR range.
3. Adjust parameters as necessary and submit a search. If searching with a target as an IP address or CIDR range, this action will be logged to the checkuser-temporary-account log which will be visible to users with the checkuser-temporary-account-log right.
4. Alongside local results, results will be returned from other wikis. If searching using an IP address as an IP address or CIDR range, then the results will be limited to the wikis where you have the ability to reveal temporary account IP addresses (as described in the Showing IPs for temporary accounts section).
