Internationalized domain names main article: Internationalized domain name The character set allowed in the domain Name system is based on ascii and does not allow the representation of names and words of many languages in their native scripts or alphabets. Icann approved the Internationalized domain name (idna) system, which maps Unicode strings used in application user interfaces into the valid dns character set by an encoding called Punycode. For example, kø is mapped. Many registries have adopted idna.

Each label is separated by a full stop (dot). 'sos' is said to be a sub-domain of and 'state' a sub-domain of etc. In general, subdomains are domains subordinate to their parent domain. An example of very deep levels of subdomain ordering are the ipv6 reverse resolution dns zones,. G., pa, which is the reverse dns resolution domain name for the ip address of a loopback interface, or the localhost name. Second-level (or lower-level, depending on the established parent hierarchy) domain names are often created based on the name of a company (e.g., bbc product or service (e.g. Below these levels, the next domain name component has been used to designate a particular host server. Therefore, m might be an ftp server, m would be a world Wide web server, and m could be an email server, each intended to perform only the implied function.

The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node m as a subdomain of the com domain, and www is a label to create m, a subdomain. Each label may contain from 1 to 63 octets.
