What Is Rip 1 & 2?
A routing protocol refers to a protocol, or standard, that dictates how routers in computer networks interface with each other. RIP, or Routing Information Protocol, is a routing protocol used in LANs and WANs. Versions of RIP include RIP 1 and RIP 2.

RIP 1
-
RIP 1, the original RIP specification, uses classful network routing. Classful networks, utilized largely for Internet routing from 1981 until 1993 when Classless Inter-Domain Routing was introduced, divides Internet address space into classes, which in turn defines network size. RIP 1 carries no subnetmask information or routing prefixes in an Internet Protocol subnetwork, thereby rendering it impossible to contain different sized subnetworks within the same network class.
RIP 2
-
RIP 2, also known as RIPv2, was developed in 1993 in response to deficiencies in the RIP 1 standard. RIP 2 carries subnetwork and subnetmask information and supports CIDR, or Classless Inter-Domain Routing. Classless Inter-Domain Routing refers to a system of methods used to distribute or allocate IP addresses and route Internet Protocol packets, which are groups of data.

RIPng
-
RIPng, or RIP next generation, refers to an extension of RIP 2 developed to support the next generation Internet Protocol, or IPv6. IPv6, short for Internet Protocol version 6, the successor to the IPv4 protocol, is used for packet-switched internetworking.
