[edit] Failsafes against large ranges

Are there failsafes so that the IP range *.*.*.* isn't blocked? --ÆAUSSIEevilÆ 22:21, 28 November 2006 (UTC)

Yes. MediaWiki does not allow range blocks affecting more than 65,536 IP addresses; that is, it allows a maximum CIDR range of /16, or 0.0.0.0–0.0.255.255. Blocking every possible IP address would require 65,025 individual range blocks. For more information, see m:Range blocks. —{admin} Pathoschild 05:49, 29 November 2006 (UTC)
