For what purpose are IPv4 addresses utilized?

An IPv4 address is used to uniquely identify a device on an IP network.

Which statement describes one purpose of the subnet mask setting for a host?

It is used to determine to which network the host is connected.

Which statement describes IPv4 addressing?

Routers use the full 32-bit IP address to determine the location of each individual host. The network portion of a destination IP address is obtained by performing an AND operation between a host IP address and a subnet mask.
