Range blocks[edit]

The MediaWiki software allows sysops to block entire ranges of IP addresses. Using CIDR notation, enter an IP range between /16 and /31 (inclusive; MediaWiki does not support blocking larger ranges). If you are unfamiliar with CIDR and binary arithmetic, then you should not block ranges.

A properly-applied range block will remove editing privileges from all persons who connect from an IP in the affected range. As a result, it may unintentionally block valued contributors, so it may be worthwhile to consult a checkuser before applying a range block.

Range blocks are a drastic measure, and should only be used for brief periods as a last resort. Poorly-applied range blocks can shut out entire nations!
