.csnet was a pseudo-domain-style suffix used in the late 1980s when identifying a hostname not connected directly to the Internet but possibly reachable through inter-network gateways. In this case, it indicated that the hostname preceding it was reachable via the CSNET network. This was one of several apparent "top-level domains" that were not actually in the Internet root, but were sometimes used in addresses during the time when non-Internet networks remained in wide use. Of these, .arpa was the only one ever actually added to the Internet root, where it continues to exist in a redesignated purpose of "Address and Routing Parameter Area".
