DNS Namespace

Did you know that the entire DNS namespace is represented by a single period. The is called the ROOT DOMAIN. This period is located at the far right of the Full Qualified Domain Name (FQDN). Many of us including myself do not enter it, it is just assumed or not known at all.

Example

www.google.com and www.google.com. (<–Noticed the period) represents the same FQDN.

Go ahead and try it for yourself.

I included a picture on how DNS works.
