  • ISPs use Domain Name Service to change a user IP address into a public IP address that can be used on the Internet.
  • Both users must be using the same Internet Service Provider.
  • Both users must be on the same network.
  • ISPs use Network Address Translation to change a user IP address into an address that can be used on the Internet.

Explanation: As user traffic from behind an ISP firewall reaches the gateway device, Network Address Translation changes private IP addresses into a public, routable IP address. Private user addresses remain hidden from the public Internet, and thus more than one user can have the same private IP address, regardless of ISP.
