Domain Services The DNS service enables client computers on your network to register and resolve DNS domain names. These names are used to find and access resources offered by other computers on your network or other networks, such as the Internet. Domain Name Service (DNS) is the service used to convert human readable names of hosts to IP addresses.

Host names are not case sensitive and can contain alphabetic or numeric letters or the hyphen. Avoid the underscore. Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses.

Every time if use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.tiainterweb.com might translate to 185.195.242.4. The DNS is, in fact, its own network if one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.
