NAI meaning in Networking ?

Answer: What is Network Access Identifier mean?

In computer networking, the Network Access Identifier (NAI) is a standard way of identifying users who request access to a network. The standard syntax is "user@realm". Sample NAIs include (from RFC 4282):

bobjoe@example.comfred@foo-9.example.comfred.smith@example.comfred_smith@example.comfred$@example.comfred=?#$&*+-/^smith@example.comeng.example.net!nancy@example.neteng%nancy@example.net@privatecorp.example.net\(user\)@example.netalice@xn--tmonesimerkki-bfbb.example.net

Network Access Identifiers were originally defined in RFC 2486, which was superseded by RFC 4282, which has been superseded by RFC 7542. The latter RFC is the current standard for the NAI. NAIs are commonly found as user identifiers in the RADIUS and Diameter network access protocols and the EAP authentication protocol.
