What are CIDR and an IP Address?

[Robyn Jones]

Hello,

The term just caught my attention so I wanted to know more about it.

[Aaron Martin]

CIDR, or classless inter-domain routing, is a set of IP addresses that a network use.

[Jamie Lee]

A CIDR address resembles an IP address, with the exception that it finishes with a slash and a number. The amount following the slash indicates how many addresses are included in the range.

[Emerson Abby]

To replace the previous classful network addressing architecture on the Internet, the Internet Engineering Task Force introduced CIDR in 1993.

[Milo Adey]

Its purpose was to reduce the expansion of routing tables on routers throughout the Internet and to contribute to a slower rate of IPv4 address exhaustion.

Is CIDR notation related to this?

Is CIDR notation related to this?

Yes.

[Hazel Williams]

It is a new way to describe IP addresses by CIDR, which is now referred to as CIDR notation.

[Emma Peterson]

An address or routing prefix is written with a suffix that specifies the number of bits of the prefix, such as 192.0.2.0/24 for IPv4 and 2001:db8::/32 for IPv6.
