You could add a path* component that specifically references the host computer.
You can add a portthat shows where the TCP connection is made on the remote host machine.
You could add a fragment(AKA: reference) that could specify a specific section you are looking for.

Components of domain names are separated by periods or dots. The three letter extension at the end describes type of domain such Google (www.Google.com), or Government (www.gov.ca) etc. the "Google" and "gov" are the domains.

Email addresses are a type of electronic mailboxes used to send and receive messages, all addresses follow the same format which is : username@domain (i.e. jdoe@gmail.com). The major difference between addresses and URL's are the absence of the "@" symbol.
