This template accepts IPv4 or IPv6 addresses as input and displays minimum-sized blocks of addresses that cover all of the inputs. The result uses CIDR notation and can be used by an administrator to block a range of IP addresses. The template can be used by editing any page, inserting the template, and previewing the result.
These groups, commonly called CIDR blocks, share an initial sequence of bits in the binary representation of their IP addresses. IPv4 CIDR blocks are identified using a syntax similar to that of IPv4 addresses: a dotted-decimal address, followed by a slash, then a number from 0 to 32, i.e., a.b.c.d / n. The dotted decimal portion is the IPv4 ...
Some large / 8 blocks of IPv4 addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), or a regional Internet registry.
If not empty or <>0: positions the strings with links below the IP, otherwise these are following the IP on the same line. Should be used within a block element, such as a table cell, as the links will center align. Parameters that are not used, may be left empty. Ranges There are two types of IP ranges CIDR ranges, e.g. 123.123.123.0/24; Non ...

The subnet mask or CIDR notation determines how the IP address is divided into network and host parts. The term subnet mask is only used within IPv4. Both IP versions however use the CIDR concept and notation. In this, the IP address is followed by a slash and the number (in decimal) of bits used for the network part, also called the routing ...
Twinkle – A comprehensive block+template tool. Allows you to choose a preset that auto-supplies the standard block duration, block summary, and template to issue to the user. You will see different presets and options when blocking IPs versus accounts. You can also use this gadget just to template the user and not block, and vice versa.
