The Address Family Identifier (AFI) is a term used in the context of network protocols and telecommunications to specify the type of network address being used in a particular packet or connection. It is most commonly associated with the Internet Protocol (IP), particularly in routing protocols such as Open Shortest Path First (OSPF) or Border Gateway Protocol (BGP).
