for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328for IPv4. The updates for IPv6 are specified as OSPF Version 3 in RFC 5340 . OSPF is perhaps the most widely used interior gateway protocol (IGP) in large enterprise networks. IS-IS, another link-state dynamic routing protocol, is more common in large service provider networks.

In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-bit number
