IP address
An IP address is a numeric identifier assigned to a device on a network, used to route data to and from that specific device.
Prerequisite: Domain Name System
What matters
Every request on the internet is ultimately routed using IP addresses; domain names exist only as a human-friendly layer on top of this numeric addressing.
Example
A web server might have the IP address 93.184.216.34, which is what DNS resolves 'example.com' to behind the scenes.
Common misconception
A device's IP address is not always permanent; many devices are assigned a different address each time they connect to a network.
Recall question
What is the actual purpose of an IP address on a network?
