Use the form below to block write access from a specific IP address, IP range (see range blocks) or username. This should be done to prevent vandalism, damage to the project or other disruptive behaviour; and in accordance with policy. Select a block reason from the dropdown below or fill in a specific reason (for example, citing particular pages that were vandalized).
You can block IP address ranges using the CIDR syntax. The largest allowed range is /$1 for IPv4 and /$2 for IPv6.
