What is a Hostname?
A hostname can be thought of as a name, created with a-z and/or 0-9 characters, that represent an IP address and is in this way an internet address. It has many similarities as a domain name, but does more often represent a user’s (a.k.a. “client” or “visitor”) IP address than a server IP address. Very often a hostname can be used instead of an IP address. One reason for hostnames existence is that they make it easier to remember and recognize the IP addresses that they represent. However, an IP address is not guaranteed to have a hostname associated with it. Similarly a server’s IP address is not guaranteed to have a domain name associated with it.
