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. There is no need to save the edit. As an example, you could edit your sandbox and replace its contents with
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 ...
Before 2001, the in-addr.arpa zones for the private networks [1] were delegated to a single instance of name servers, blackhole-1.iana.org and blackhole-2.iana.org, called the blackhole servers. The IANA -run servers were under increasing load from improperly-configured NAT networks, leaking out reverse DNS queries, also causing unnecessary ...
If you block an IP address in any of the following ranges, you are required to immediately notify the Wikimedia Foundation Communications Committee.These ranges are allocated to major governmental organizations and blocks of these organizations have political and public relations implications that must be managed by the Foundation's press relations team.
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.
Internetwork control block Addresses in the range 224.0.1.0 to 224.0.1.255 are individually assigned by IANA and designated as the internetwork control block. This block of addresses is used for traffic that must be routed through the public Internet, such as for applications of the Network Time Protocol using 224.0.1.1. AD-HOC block

The block 169.254.0.0 / 16 was allocated for this purpose. [6] [7] If a host on an IEEE 802 network cannot obtain a network address via DHCP, an address from 169.254.1.0 to 169.254.254.255 [Note 2] may be assigned pseudorandomly. The standard prescribes that address collisions must be handled gracefully.
