This is the place to request sockpuppet checks and other investigations requiring access to the Checkuser privilege. Possible alternatives are listed below.

A
Blatant attack or vandalism accounts, need IP block
Choose the code letter that best fits your request. Provide evidence such as diff links as required or requested. Note that some code letters inherently require specific evidence.
When listing suspected accounts or IP addresses, use the {{checkuser}} or {{checkip}} templates. Please do not use this template in a section header.
You may add your request to the top of the #Outstanding requests section, by adding {{Wikipedia:Requests for checkuser/Case/CASENAMEHERE}}. If you do not, clerks should check for pages in Category:Checkuser requests to be listed and will do this for you.
Responses will be brief in order to comply with Wikipedia's privacy policy. Likewise, the privacy policy often prevents us from running a check which has the effect of revealing IP addresses.
Due to technical factors, results are not always clear.
Check back regularly to see the outcome of your request.
If you feel that a checkuser has led to a violation of the Wikimedia Foundation privacy policy regarding yourself, please refer the case to the Ombudsman commission.
Vandal and attack accounts may be listed here for the purpose of identifying and blocking the underlying IP address or open proxy. Requests to confirm sockpuppets of known users should be listed in the sockpuppet section above.
If you already know the IP address of the suspected open proxy, list it at Wikipedia:Open Proxies instead.
Use === Subsections ===; do not create subpages.
List user names using the {{checkuser|username}} template. Add new reports to the top of the section.
Requests may be acted on or declined according to the discretion of the checkuser admins. Responses will be noted here. Specific evidence of abuse in the form of diffs may be required so as to avoid the impression of fishing for evidence.
Answered requests will be moved to Wikipedia:Requests for checkuser/IP check/Archive for 7 days, after which they will be deleted. No separate archive (other than the page history) will be maintained.
Non-compliant requests
Requests that do not follow the instructions at the top of the page will be moved here. Common reasons for noncompliance include:
Did not cite a code letter, or cite more than one code letter.
Did not cite any supporting diffs if the code letter requires diffs.
Included IP addresses.
The specific deficiencies may be noted with Additional information needed. Cases which are corrected may be moved back to the pending section. Cases which are not corrected will be deleted after 3 days.
Please note that meeting these three criteria does not ensure that your check will be run. The checkusers retain final discretion over all cases.
