CIDR notation is a compact representation of an IP address and its associated network mask. The notation was invented by Phil Karn in the 1980s. [ 9 ] [ 10 ] CIDR notation specifies an IP address, a slash ('/') character, and a decimal number.
This notation was introduced with Classless Inter-Domain Routing (CIDR). [2] In IPv6 this is the only standards-based form to denote network or routing prefixes. For example, the IPv4 network 192.0.2.0 with the subnet mask 255.255.255.0 is written as 192.0.2.0 / 24 , and the IPv6 notation 2001:db8:: / 32 designates the address 2001:db8:: and ...
Restricted to networks used by the organization administering the local network. (For example, these addresses might be used over VPNs; when packets for this group are routed over the public internet (where these addresses are not valid), they would have to be encapsulated in some other protocol.) ffxe::/16: 224.0.1.0-238.255.255.255: Global scope
A classful network is an obsolete network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits.
