Fully-Qualified Host Name

from Wikipedia, the free encyclopedia

A fully-qualified host name ( FQHN , German "fully specified hostname") is a host name , either as a fully qualified name of a domain ( Fully-Qualified Domain Name , FQDN ) or a numeric IP address of a computer is shown. The FQHN uniquely identifies a specific computer.

An FQHN of a computer with the host name “ host1 ” of the company with the domain “ example.com ” can be accessed through the FQDN “ host1.example.com. "Are designated. Note the last point after the " com " top-level domain. Another FQHN can be the IP address of the computer (e.g. " 192.0.2.123 ").

In contrast to the FQDN, the Partially Qualified Domain Name (PQDN) is a relative name for a domain. This does not indicate the full path to the top-level domain. Often this is used for simple host names. For example, " host1 " is a PQDN to " host1.example.com ". Note the lack of the last point.

The term FQHN is used in the two RFCs 1153 ( Digest Message Format from 1990) and 2109 ( HTTP State Management Mechanism from 1997). RFC 2109 has since been replaced by RFC 2965 ( HTTP State Management Mechanism from 2000), in which the term no longer appears.
