The term Domain name is a name that identifies a computer or computers on the internet. These names appear as a part of a web site’s URL. This type of domain is called a hostname. A hostname is also called a sitename, a unique name by which a network-attached device which consists of computer, file server, network storage device, fax machine, etc. is known on a network. It is used by many of the networking programs to identify the machine. The domain name is also used by NIS/YP.
Hostname is an alternative name given to a computer when it is connected to the internet. It is used instead of the unique Internet address which is in the form of four numbers separated by dots. The hostname is an alias, nickname, and it is easier to remember than the number. It has a maximum 255 character string. In hostname qualification, it is desirable to catch unqualified hostnames specified in sender addresses. For example, in gatewaying between two networks where one requires fully qualified domain names. On an Internet-UUCP relay, unqualified hostnames should be mapped to the UUCP domain by default. Other addresses modifications than these are questionable.
The /usr/lib/smail/qualify file tells smail which domain names to pin onto which hostnames. Entries in the qualify file consists of a hostname beginning in column one, followed by domain name. Lines containing a hash sign as its first non-white character are considered comments. Entries are searched in the order they appear in. If no qualify file exists, no hostname qualification is performed at all. At the Virtual Brewery, all hosts have been set up to use fully qualified domain names in the sender's addresses. Unqualified recipient addresses are considered to be in the UUCP domain, so only a single entry in the qualify file is needed.
On the internet, hostname is a domain name assigned to the host. This is usually a combination of the host's local name with its parent domain's name. This kind of hostname is translated into an IP address via the local host file. It is very possible for a single host to have several hostnames but generally the operating system (OS) of the host prefers to have one hostname that the host uses for it. In choosing a good hostnames are outlined in RFC 1178. The folklore interest of hostnames stems from the creativity and humor they often display. Interpreting a sitename is not unlike interpreting a vanity license plate; one has to mentally unpack it, allowing for mono-case and length restrictions and the lack of whitespace. Mythological references, cartoon characters, animal names, and allusions to sci-fi literature are possibly the most popular sources for sitenames. It is also likely to guess a hostname for a particular institution. This is useful if you want to know if they operate network services like anonymous FTP, World-Wide Web or finger. Try the institution's name or abbreviations with the appropriate domain appended. You can also use the ping command as a fastest way to test whether a hostname is valid.
