In IPv4 addressing, which portion is used to identify the subnet?

Explanation:
In IPv4 addressing, the address is split into a network portion and a host portion. The network portion, as defined by the subnet mask, identifies which subnet the device belongs to. Routers use this network portion to determine where to forward packets, and all devices within the same subnet share that network portion. The host portion identifies the specific device within that subnet. The MAC portion is a hardware address used on the local link, and the payload is just the data carried by the packet. So the subnet is identified by the network portion of the IP address.
