DNS System

Many thousands of DNS link together to form the most active distributed database in the world, known as the DNS System. A relatively small number of high-level "root" DNS handle the several hundred top-level domains (eg. .nz, .uk, .com). A request for a .nz domain name (eg. dnc.org.nz) is referred by the root DNS to the .nz DNS. The .nz DNS, which is managed and operated by NZRS and updated regularly from the register every day, will refer the request to one of countless other DNS that exist within hosting companies. It is therefore important that the name server (DNS) details for individual domain names in the register are kept up to date. Missing or incorrect name server details will make a domain name unusable for a web site, email address, or any other purpose.
