6. How it Operates?
• A user opens a web browser, enters www.example.com
• The request for www.example.com is routed to a DNS resolver, which is typically managed by the
user's internet service provider (ISP)
• The DNS resolver forwards the request to a DNS root name server and to one of the TLD name
servers for .com domains. Which respond with the names of Route 53 name servers that are
associated with the example.com domain.
• The DNS resolver caches the Route 53 name servers for a faster delivery of similar next request
