Control which IP address(s) a domain resolves to!
Example Virtual DNS
|
Whenever a browser first opens, it reads the computer's
hosts file. The
hosts file contains IP addresses associated to domain names. The browser adds those associations to it's DNS memory. From then on (during that session) the browser will not ask the World Wide Web's DNS system to resolve IP addresses for the domain names it has in it's DNS memory. Virtual DNS is an application that manages the hosts file, adding, editing, and removing entries quickly and efficiently.
Moving to a new server?
Resolve to a new IP addresse before changing the World Wide Web's DNS system.
In the example www.editwrxpro.com is associated with two IP addresses. The 196.223.164.203 IP is disabled, the 206.222.19.194 is enabled. That tells the browser to find editwrxpro.com on the 206.222.19.196 server. Although the public will still find editwrxpro.com at the 196.223.164.203 IP, you can now access it at 206.222.19.194 while testing the new installation. With Virtual DNS you can easily turn an IP on or off at will.
Using a local development server?
If you have a localhost development server on your computer you can easily snap back and forth from the local server to the web server. In the example, editwrxpro.com resolves to the local computer's 127.0.0.1 IP, while www.editwrxpro.com resolves to the web server's 206.222.19.194 IP. Simply changing the browser's address field from http://editwrxpro.com to http://www.editwrxpro.com will move from the local copy of the domain to the web server copy of the domain. You can even setup a development subdomain and move to it by using http://dev.editwrxpro.com. This use of VirtualDNS is perfect for developing and maintaining dynamic websites using cgi, asp, or php because the local domain and the web domain can be identical in every way, and you can easily move from one environment to the other.
