Abstract
This document specifies the telnet: Uniform Resource Identifier (URI)
scheme that was originally specified in RFC 1738. The purpose of
this document is to allow RFC 1738 to be moved to historic while
keeping the information about the scheme on standards track.
1. Introduction
URIs are were previously defined in RFC 2396 [RFC2396], which was
updated by draft-fielding-uri-rfc2396bis [2396bis]. Those documents
also specify how to define schemes for URIs.

Internet-Draft The telnet: Scheme August 2004
The first definition for many URI schemes appeared in RFC 1738
[RFC1738]. Because that document has been moved to Historic status,
this document copies the telnet: scheme from it to allow that
material to remain on standards track.
2. Scheme Definition
The Telnet URL scheme is used to designate interactive services that
may be accessed by the Telnet protocol.
A telnet URL takes the form:
telnet://<user>:<password>@<host>:<port>/
The final "/" character may be omitted. If :<port> is omitted, the
port defaults to 23. The :<password> can be omitted, as well as the
whole <user>:<password> part.
This URL does not designate a data object, but rather an interactive
service. Remote interactive services vary widely in the means by
which they allow remote logins; in practice, the <user> and
<password> supplied are advisory only: clients accessing a telnet URL
merely advise the user of the suggested username and password.
3. Security Considerations
There are many security considerations for URI schemes discussed in
draft-fielding-uri-rfc2396bis [2396bis].
