Internet Hostname

In the Internet world, a hostname is actually a domain name which is a unique name or Unique Resource Locator (URL). Most of the time they are combined with the "host" local name and "domain" name, that will look something like this "www.weaccuse.net". Domain name can only be a hostname when the particular site or address exist. For example, "abc.weaccuse.net" is not a hostname simply because this page does not exist, unlike "www.weaccuse.net" which is a true hostname.

This happens when an Internet Protocol (IP) address is assigned to the particular local hostname using the Domain Name Server (DNS) where the owner of the domain can change it through its domain registrar. A domain name or a hostname can both be used to tell people about a website and they are always interchangeable, although they have some differences in between. Plus, a domain is possible to have more than one hostname and there are a few restrictions when choosing a domain name.

Hostname or domain name consists or at least two or more labels and this label is in fact the part separated by dots. Therefore, the entire domain name has only 255 characters as its limit and each label is valid to enter at least 1 to 63 characters long. The most important part is its input, where only letters from 'a' to 'z', digits from '0' to '9' and hyphens are allowed. Special characters (except IDNs), symbols, spaces and label that ends with a hyphen are all restricted.
