DNS is the magic that allows the Internet to function. It helps people and computers to communicate, even though they speak very different languages. The people speak with names and the computers with IP addresses and codes. Now we will examine one element of that “magic” – the Primary DNS zone!

The Primary DNS zone is an administrative unit of the DNS that permits control on the part (zone) that the upper level in the DNS hierarchy allowed it. A higher-level administrator delegates zones to lower levels. The Root servers to TLD servers, the TLD servers to Primary Authoritative name servers (secondary domain name), etc.
