Неопходно је да имате одређена знања о томе како мреже и ИП означавање функционише, као и о бинарној аритметици. Ако не поседујете ова знања обратите се за помоћ неком другом администратору.
[[Special:Ipblocklist]] contains a list of all currently blocked users and IPs. Sysops will see a link to (<font color=blue>[http://en.wikipedia.org/w/index.php?title=Special:Ipblocklist&action=unblock unblock]</font>) next to each user. After clicking this, you should type in the reason that you are unblocking the user and then click the ''Unblock this address'' button.
Sysops are technically able to unblock themselves by following this procedure but should absolutely ''not'' do so unless they were autoblocked as a result of a block on some other user (or bot) that they share an IP with. Otherwise, if an admin feels they were not blocked for a valid reason, they should contact the blocking admin, another admin, or the mailing list and ask to be unblocked. Self-unblocking without convincingly good reason has resulted in several users losing their sysop privileges.
