Make sure you have a good reason for the check. It will only be accepted to counter vandalism or disruption to Wikimedia wikis. Valid reasons include needing a block of the underlying IP or IP range, disruptive sockpuppetry, vote-stacking, and similar disruption where the technical evidence from running a check would prevent or reduce further disruption.
Be specific in your reasons. Ambiguous or insufficient reasons will cause delays. Explain the disruption and why you believe the accounts are related, ideally using diff links or other evidence.
Make sure there are no local checkusers or policies.

Inconclusive For checkuser, usernames from months ago is pointless, all that we can check is data for the last three months, and in this situation you are going to need to provide better data for any checkuser investigation above an edit here and there, over the diverse period. For an article, if there is problem editing, then it is better to deal with it outside of checkuser, checkuser generally is of little value unless you are looking to place a block. I am not certain what else is expected to happen in this case. @Elph: can you assist the user in the background to checkuser, useful article history. — billinghurstsDrewth 13:54, 4 October 2015 (UTC)
Confirmed. And you have two other sleepers: AdmerOFVolleyball and JESSARICAN2. QuiteUnusual (talk) 07:22, 1 October 2015 (UTC)
I believe the IP for these is 22.214.171.124. Can QuiteUnusual confirm if this IP is a high school, college, or university in the Philippines? --Marshallsumter (talk) 12:21, 3 October 2015 (UTC)
I can't disclose the IP. As for checking the ownership or geolocation of an IP, if you look at the contributions page for the IP you will find links to a number of useful tools. QuiteUnusual (talk) 18:09, 3 October 2015 (UTC)
