Briefly describe private IPv4 addresses.

Why are they important? 

Expert Solution
Step 1

Answer:

  • Your device will have a private IP address if it is assigned one by your network router. A private IP address (also referred to as a private network address) is assigned to each device on the same internal network so that they can communicate with each other.
  • Private IP addresses allow devices on the same network to communicate with each other without having to connect to the Internet.
  • The usage of private IPs helps to increase network security by making it more difficult for an outside host or user to establish a connection. It's because of this that you can print documents from your wireless printer at home, but your neighbour can't unintentionally transmit their files to your printer by mistake.
