IP address(Internet Protocol address) is an identification number assigned to each device to identify a device on the PC or network by IP. It is the same as each phone number is different, each with a unique identification number. In order to connect to each other on the network, IP address is always necessary.

Type of IP address

Usually, there are two kinds of IP address: private IP address used in households and enterprises, and “Global IP address” used in the connect between a Router and Internet.

Private IP address

It is the IP address of the network that is assigned to general households or companies. Also called Local IP address. It is assigned to PCs and devices on the local network by the router.

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

With the private IP address alone, the Internet can not connect. Internet can be used by mutually converting “Private IP address” and “Global IP address” with router equipment.

Global IP address

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.
