In a TCP/IP-based network, an IP address specifies a:
A. network connection.
B. router/gateway.
C. computer in the network.
D. device on the network.
Answer / guest
Answer: A
An IP address, specifies a network connection. An IP address
encodes both a network and a host on that network, it does
not specify an individual computer, but a connection to a
network. A router/gateway connects two networks and will
have two IP addresses. Hence, an IP address cannot specify a
router. A computer in the network can be connected to other
networks as well. It will then use many IP addresses. Such
computers are called multi-homed hosts. Here again an IP
address cannot refer to the computer. IP addresses do not
refer to individual devices on the network, but refer to the
connections by which they are connected to the network.
