Hostname

What is a hostname?

A hostname is a label assigned to a device connected to a network, such as a computer or server, which is used to identify the device within a specific domain. It forms part of the fully qualified domain name (FQDN), which uniquely specifies a device's location in the hierarchical Domain Name System (DNS). For example, in the FQDN "server1.example.com," "server1" is the hostname, "example" is the domain, and ".com" is the top-level domain. Hostnames allow devices to be easily located and communicated with over the internet or a local network, facilitating the resolution of human-readable names to IP addresses.
