Glossary
A names server or DNS server is a computer connected to the Internet. It contains information about the services related to a domain name and answers any queries about this information. For example, it translates a domain name into an IP address to enable access to a website/s and/or email inboxes linked to a domain name.
An IP address is a technical identifier, assigned to each piece of equipment connected to the Internet, and that these use to communicate with each other. There are currently two formats of IP addresses: IPv6 and its predecessor IPv4.
A domain name is a functional identifier that is unique, understandable, and memorable to and by human beings. It enables technical information to be obtained, such as the IP address of websites or electronic mailboxes, by asking a names server (DNS server).
