A group of computers whose {hostnames} share a common suffix, the "domain name".

I can't think why it should.) monkey@smacky:~% dict hostname - From The Free On-line Dictionary of Computing (09 FEB 02) [foldoc]: hostname 1. (Or "sitename"). The unique name by which a computer is known on a {network}, used to identify it in {electronic mail}, {Usenet} {news}, or other forms of electronic information interchange. On {Internet} the hostname is an {ASCII} string, e.g. "foldoc.doc.ic.ac.uk" which, consists of a local part (foldoc) and a {domain} name (doc.ic.ac.uk). > > Let's say you have names "fubar.org", "alpha.fubar.org", and > > "beta.fubar.org".

A domain name is just a name, but a hostname is a label applied to something that exists. Every domain name can be a hostname if a computer responds to that name. > > Let's say you have names "fubar.org", "alpha.fubar.org", and > > "beta.fubar.org". All three names resolve to 1.2.3.4.
