File Transfer Protocol HOST Command for Virtual Hosts

Overview

RFC 7151, “File Transfer Protocol HOST Command for Virtual Hosts”, is a Proposed Standard document published in March 2014 by P. Hethmon, R. McMurray. It updates RFC 959. The canonical text is published by the RFC Editor.

Abstract

The File Transfer Protocol, as defined in RFC 959, does not provide a way for FTP clients and servers to differentiate between multiple DNS names that are registered for a single IP address. This document defines a new FTP command that provides a mechanism for FTP clients and servers to identify individual virtual hosts on an FTP server.

Abstract as published in the RFC, via rfc-editor.org.

What “Proposed Standard” means
