What is network portion and host portion?

In an IP address, the network portion identifies the specific network to which a device belongs, while the host portion identifies the individual device within that network. This structure allows for efficient routing of data across the internet by segregating the address into parts that signify the network and the specific device. The division between the network and host portions is determined by the subnet mask, which specifies how many bits are allocated to each portion. For example, in the IP address 192.168.1.10 with a subnet mask of 255.255.255.0, "192.168.1" represents the network portion, and "10" represents the host portion.
