IP Address

Definition:

A number set that identifies a computer on the Internet, so another computer can find and connect to it.

 

There are two types of of IP address, (1) older IPv4 and (2) Newer IPv6. Many machines and providers still only support IPv4, while now new IPv4 addresses are no longer available in many countries. You can still get an IPv4 by transferring from others.

 

IPv4 addresses consists of 4 numbers separated by dots. Each number ranges from 0 ~255. Examples are: 139.130.4.5

 

IPv4 addresses consists of 8 numbers separated by dots. Each number is four hexadecimal (16) digits (0-9,a,b,c,d,e,f). Examples are: 2001:0db8:85a3:0000:0000:8a2e:0370:7334
