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 the 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). The hostname is translated into an Internet address either via the {hosts file}, NIS or by the Domain Name System (DNS) or resolver. It is possible for one computer to have several hostnames (aliases) though one is designated as its canonical name. It is often possible 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. First try the institution's name or obvious abbreviations thereof, with the appropriate domain appended, e.g. "mit.edu". If this fails, prepend "ftp." or "www." as appropriate, e.g. "www.data-io.com". You can use the ping command as a quick way to test whether a hostname is valid. The folklore interest of hostnames stems from the creativity and humour they often display. Interpreting a sitename is not unlike interpreting a vanity licence plate; one has to mentally unpack it, allowing for mono-case and length restrictions and the lack of whitespace. Hacker tradition deprecates dull, institutional-sounding names in favour of punchy, humorous, and clever coinages (except that it is considered appropriate for the official public gateway machine of an organisation to bear the organisation's name or acronym). Mythological references, cartoon characters, animal names, and allusions to SF or fantasy literature are probably the most popular sources for sitenames (in roughly descending order). The obligatory comment is Harris's Lament: "All the good ones are taken!" See also network address. 2. Berkeley Unix command to set and get the application level name used by the host. Unix manual page: hostname(1). (1995-02-16)

<programming, operating system> A variable that is bound in the current environment. When evaluating an expression in some environment, the evaluation of a variable consists of looking up its name in the environment and substituting its value. Most programming languages have some concept of an environment but in Unix shell scripts it has a specific meaning slightly different from other contexts. In shell scripts, environment variables are one kind of shell variable. They differ from local variables and command line arguments in that they are inheritted by a child process. Examples are the PATH variable that tells the shell the file system paths to search to find command executables and the TZ variable which contains the local time zone. The variable called "SHELL" specifies the type of shell being used. These variables are used by commands or shell scripts to discover things about the environment they are operating in. Environment variables can be changed or created by the user or a program. To see a list of environment variables type "setenv" at the csh or tcsh prompt or "set" at the sh, bash, jsh or ksh prompt. In other programming languages, e.g. functional programming languages, the environment is extended with new bindings when a function's parameters are bound to its {actual arguments} or when new variables are declared. In a block-structured procedural language, the environment usually consists of a linked list of activation records. (1999-01-26)

Hostname

In computer networking, a hostname (archaically nodename) is a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication, such as the World Wide Web. Hostnames may be simple names consisting of a single word or phrase, or they may be structured. Each hostname usually has at least one numeric network address associated with it for routing packets for performance and other reasons.

Internet hostnames may have appended the name of a Domain Name System (DNS) domain, separated from the host-specific label by a period ("dot"). In the latter form, a hostname is also called a domain name. If the domain name is completely specified, including a top-level domain of the Internet, then the hostname is said to be a fully qualified domain name (FQDN). Hostnames that include DNS domains are often stored in the Domain Name System together with the IP addresses of the host they represent for the purpose of mapping the hostname to an address, or the reverse process.
