What is a Hostname?


The term hostname refers to the unique part of a sub-domain that identifies a host on the Internet. In www.noip.com, “www” is the hostname. In that same example, noip.com is the domain name. The host portion prepended to the domain name is often referred to as the hostname, and that is how we use the term here. Our free dynamic DNS service offers free hostnames on No-IP owned domains i.e. yourhostname.ddns.net. If you would like to create hostnames using your own domain name, you will need to register a domain, and purchase Plus Managed DNS.
