MediaWiki:Blockiptext

Use the form below to make a specific IP address or username game-over. This is not a toy and should be used only to prevent vandalism. So basically, you can do whatever you want with this, as long as you give a reason. Fill in a specific reason below (for example, citing particular pages that were vandalized). This is the most important step. You can block a range of IP addresses using the CIDR syntax. Just make sure that the range doesn't go over /$1 for IPv4 or /$2 for IPv6.
