In computer networking, a hostname (archaically nodename [1]) 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.
The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.
Unix, Unix-like: Type: Command: License: Mozilla Public License 2.0: host is a simple utility for performing Domain Name System lookups. Origin.
file://path (i.e. two slashes, without a hostname) is never correct, but is often used. Further slashes in path separate directory names in a hierarchical system of directories and subdirectories. In this usage, the slash is a general, system-independent way of separating the parts, and in a particular host system it might be used as such in ...
For example, the hostname www.example.com within the domain name example.com translates to the addresses 93.184.216.34 and 2606:2800:220:1:248:1893:25c8:1946 . The DNS can be quickly and transparently updated, allowing a service's location on the network to change without affecting the end users, who continue to use the same hostname.
Unix operating systems associate both an alphanumeric name and a user or group ID with each user account or defined group of user names. The GNU C Library provides various operating system facilities that shell commands and other applications can call to resolve such names to the corresponding addresses or IDs, and vice versa.
The function getnameinfo() converts the internal binary representation of an IP address in the form of a pointer to a struct sockaddr into text strings consisting of the hostname or, if the address cannot be resolved into a name, a textual IP address representation, as well as the service port name or number. The function prototype is specified ...
Most Unix-like systems use a similar syntax. [13] POSIX allows treating a path beginning with two slashes in an implementation-defined manner, [14] though in other cases systems must treat multiple slashes as single slashes. [15] Many applications on Unix-like systems (for example, scp, rcp, and rsync) use resource definitions such as:
