A network host with an IP address of 192.168.10.200 wants to send a message to a destination computer with an assigned IP addres
s of 192.168.10.100. Which of the following will the sending host use to determine whether the destination computer is on its own network or another network?
A Subnet mask is used by the TCP/IP protocol to determine whether a host is on the local Subnet or on a remote network.
In TCP/IP, the parts of the IP address that are used as the network and host addresses are not fixed, so the destination host address 192.168.10.100 cannot be determined by the network host (192.168.10.200) unless it has more information. This information is supplied in another 32-bit number called a Subnet mask.
