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. The decimal number is the count of consecutive leading 1-bits (from left to right) in the network mask ...

The number of addresses usable for addressing specific hosts in each network is always 2 N - 2, where N is the number of rest field bits, and the subtraction of 2 adjusts for the use of the all-bits-zero host value to represent the network address and the all-bits-one host value for use as a broadcast address. Thus, for a Class C address with 8 ...
Ethernet frames with a value of 1 in the least-significant bit of the first octet [note 2] of the destination MAC address are treated as multicast frames and are flooded to all points on the network. While frames with ones in all bits of the destination address ( FF-FF-FF-FF-FF-FF ) are sometimes referred to as broadcasts , Ethernet generally ...
An example of route aggregation as a part of CIDR. A supernetwork, or supernet, is an Internet Protocol (IP) network that is formed by aggregation of multiple networks (or subnets) into a larger network. The new routing prefix for the aggregate network represents the constituent networks in a single routing table entry.
Specify lists of address ranges, e.g. in CIDR format, for various address families. Experimental. SINK 40 — Defined by the Kitchen Sink Internet Draft, but never made it to RFC status GPOS 27 RFC 1712 A more limited early version of the LOC record UINFO 100 —
Longest prefix match (also called Maximum prefix length match) refers to an algorithm used by routers in Internet Protocol (IP) networking to select an entry from a routing table. [1] Because each entry in a forwarding table may specify a sub-network, one destination address may match more than one forwarding table entry. The most specific of ...
