When we enter a URL in our browser, it sends the URL to a DNS server to look up the actual IP address. Many times a DNS server will not know the IP address of the URL and it will have to forward it on to additional DNS servers. The next server to ask is determined by reading the URL from right to left. Each section of the URL is referred to as a zone and the remainder of the URL is forwarded on to the next zone.</p>
