Private IP address

The private IP address can not be accessed directly from the Internet. Usually, the most used IP address is “192.168.XX“.

It is said to be a Public IP address, and it is an IP address published to the outside. This IP address provided by an ISP(Internet Service Provider) to identify the user’s local network on the Internet.

If the user’s PC is connected directly to the Internet without going through the router, the IP address of the PC is the public IP address.
