The DNS process is suprisingly complex. Let’s take a look at how the system works, in a simple solution. Let’s say that you want to take your new browser for a spin, and go to http://www.excalibursheath.com
How does your browser know what server to load the website from? The answer is DNS!
The DNS Process in Simplified Terms goes like this:
- Web Browser Asks the Computer do you know the address for www.excalibursheath.com?
- The computer asks the resolving name server, usually at your Internet Service Provider what’s the IP Address for www.excalibursheath.com
- The resolving name server asks the root name server for the IP Address. The root server says check the TLD (Top Level Domain) name servers.
- The resolving name server then asks the TLD server for the IP Address. The TLD server then says to check with the Authoritative Name Server.
- The Authoritative name server says the IP Address is 188.8.131.52.
