Tutorial Overview
Configuring two public DNS and Web server to host a new Website
Each system or server connected to the Internet is provided with an IP address. An IP address is made up of a series of numbers with periods in between them. The format for an IP address is: 000.000.0.0. A user can publish a website on the Internet with just an IP address. Users can type in an IP address on a Web browsers' address bar and it will direct them to the home page of the server. The numbers may be a bit hard to remember if the user wants to generate large traffic for their website. DNS is used to assign websites to IP addresses. When the user types a URL on the address bar, the system will refer to the DNS to check which IP address it corresponds to. The Web browser will then be directed to the IP address of the website.

Creating forward lookup zones for a new master DNS database server
A master DNS server is the source of the zone information during a transfer. The master DNS server can be a primary or secondary DNS server. If the master DNS server is a primary DNS server, then the zone transfer comes directly from the DNS server hosting the primary zone. If the master server is a secondary DNS server, then the zone file received from the master DNS server by means of a zone transfer is a copy of the read-only secondary zone file. The zone transfer is initiated in one of the following ways: 1-The master DNS server sends a notification (RFC 1996) to one or more secondary DNS servers of a change in the zone file. 2-When the DNS Server service on the secondary DNS server starts, or the refresh interval of the zone has expired (by default it is set to 15 minutes in the SOA RR of the zone), the secondary DNS server will query the master DNS server for the changes.
