Network Access Identifier

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 NAI's include (from RFC 4282):

          bob
          joe@example.com
          fred@foo-9.example.com
          fred.smith@example.com
          fred_smith@example.com
          fred$@example.com
          fred=?#$&*+-/^smith@example.com
          eng.example.net!nancy@example.net
          eng%nancy@example.net
          @privatecorp.example.net
          \(user\)@example.net
          alice@xn--tmonesimerkki-bfbb.example.net

Network Access Identifiers were originally defined in RFC 2486, which has been superseded by RFC 4282. The latter RFC is the current standard for the NAI.
