n e t B

Explanation: The Internet Protocol (IP) address is used by routers (at Layer 3) to identify specific deviceson a
net net net net net net net net net net net net net net net net et

network. This type of address, as opposed to a MAC address, is used across routed devices (routers)(that is,
net net net net net net net net net net net net net net net net net et

the IP address typically does not change when traffic flows through a router).
