See section Archiving below. This document is based on International Standard ISO 3166 Names . This includes 'telnet', 'ftp', and internet e-mail. If this is not preceded by FI or B, it means that the connection may be a UUCP connection. An asterisk is included after FI or B for consistency.
P stands for provisional connection.
It is generally possible to assume that wherever there is a U.S. military base, there will be a node reachable through gateways. However the connection may take place via UUCP and cost a lot of money. Those networks have therefore not been included. X.400 e-mail is usually charged to someone and if the telecommunication carrier cannot find someone to pay for the message transfer, it will reject it. As a result, those types of network have not been included in the list.
