How Public DNS Works
User enters a URL
User enters the URL www.example.com into a web browser.
Verisign Public DNS Resolver
The domain is sent to a recursive DNS resolver.
Recursive resolver starts with the root server to find where to go to get the location for the requested top level domain name.
TLD Name Server
Recursive resolver checks with the Top Level Domain (TLD) Name Server to find where to go to get the location for the authoritative server for that domain.
This server knows the exact location for the full domain name and returns the answer to the recursive resolver (IP Address 220.127.116.11).
The recursive DNS resolver returns the actual location of www.example.com to the user.
The user’s web browser loads the page from www.example.com located at 18.104.22.168
