Analysis of an example URI 
https://www.example.com:9876/about/us.html?highlight=team#management

  • The scheme https is registered with IANA and refers to the protocol "HTTP over TLS", using TCP port number 443 by default, to determine the protocol used between client and server.

  • The authority www.example.com:9876 contains a host and a port:

    • The host name www.example.com is registered with DNS (which must be accessible separately) and refers to the IP address 93.184.216.119 to find the endpoint among all reachable hosts on the Internet.

      Also, it is included in the HTTP request as the "Host" field to distinguish among multiple virtual hosts that may be provided by the server software sharing the same IP address.
