what is my fqdn
A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or host, on the Internet.The FQDN consists of two parts: the hostname and the domain name.For example, an FQDN for a hypothetical mail server might be mymail.somecollege.edu. The hostname is mymail, and the host is located within the domain somecollege.edu.n this case, www is the name of the host in the indiana.edu domain. When connecting to a host (using an SSH client, for example), you must specify the FQDN. The DNS server then resolves the hostname to its IP address by looking at its DNS table.
