Example of a Primary Domain Configuration

It will be useful to configure a sample primary domain configuration. This example sets up a domain called comedy.cartoon.net on the name server stimpy. There are various hosts in the domain that have different functions.

In the Primary Domain Name field, specify:


comedy.cartoon.net

In the Host Names/Host Addresses field, type a list of those hosts whose presence are to be broadcast to any machine that can connect to this DNS server. For this example, type ren and stimpy, and for a host called homer that resides in (located) in the DNS subdomain black.comedy.cartoon.net, type homer.black.


ren	 	 	 	 	 118.1.1.2
homer.black	 	 118.2.1.2
stimpy	 	 	 	 	 118.1.1.3

The Internet community uses conventional names for hosts that provide certain types of services, in order to make them easy to locate. For instance, the WWW server for a domain is usually known as www.domain, and an anonymous FTP server is typically called ftp.domain. On comedy.cartoon.net, ren is an FTP and WWW server, while stimpy is a name server. Standard aliases for these machines are added into the Host Aliases/Host Names field. For example:


www	 	 	 	 	 	 ren
ftp	 	 	 	 	 	 ren
ns	 	 	 	 	 	 stimpy

stimpy is going to handle mail sent to comedy.cartoon.net, so an MX record needs to be created.


comedy.cartoon.net.		 							5		 	stimpy

Finally, to the name server records, are added a single record for a host called homer that resides in a subdomain of comedy.cartoon.net called black - homer.black.comedy.cartoon.net is the name server for that domain.


black.comedy.cartoon.net. 	 	 homer.black.comedy.cartoon.net.

If a domain contains subdomains that are maintained on another DNS server, the domain data must include records for the DNS servers for the subdomains. Note that in our example, since homer resides in the black subdomain, a Host Name/Host Address record for homer had to be added so that stimpy can reach it.

There is no need to create a name server record which says that stimpy is a name server for comedy.cartoon.net, because the Netra j software does that automatically. Next time you visit this form to modify the domain, the following record shows up next to the one for homer.
