IP Address
IP addresses identify individual devices on a network. Every networking device (including computers,
servers, routers, printers, etc.) needs an IP address to communicate across the network. These
networking devices are also known as hosts.

Subnet Mask

Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet
masks to divide one network into multiple sub-networks.
