What it concludes

• An IP address is like a phone number for electronic devices so they can communicate with each other over a network.
• Without an IP address, devices cannot talk to one another or connect to the internet.
• The router functions as the default gateway to allow devices to communicate outside their local network.
• The subnet mask determines which part of the IP address is the network portion and which part is the host portion.
• The first IP address in a network is the network address and the last IP address is the broadcast address.
