Classless Inter-Domain Routing (CIDR / ˈ s aɪ d ər, ˈ s ɪ-/) is a method for allocating IP addresses for IP routing. The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous classful network addressing architecture on the Internet .

Range contributions are now supported in MediaWiki core. Simply enter the range at Special:Contributions. You can also do a wildcard search (e.g. 83.217.178.*) using the Contribsrange gadget gadget. Enable "Allow /16, /24 and /27 – /32 CIDR ranges" at Special:Preferences#mw-prefsection-gadgets under "Advanced".
