How is it used? Which IP address are you confused?
First of all, it is important to understand that there are so many IP addresses in the world. To truly understand the reason, you need to understand the binary and decimals. Binary numbers are simple: 0 and 1. However, decimal numbers are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
I will not explain it in much detail, but the IP address is a decimal number of the binary address.
IP address 0.0.0.0 (decimal number) = 00000000.00000000.00000000.00000000 (binary)
IP address 255.255.255.255 (decimal number) = 11111111.11111111.11111111.11111111 (binary number)[url = “http://en.wikipedia.org/wiki/Subnetwork”%5D Even with subnetting [/ url], by assigning one IP address to all computers and devices connected to the Internet In the world it will be impossible, we will simply be carried out!
Therefore, a simple solution to this is called “[url =” http://en.wikipedia.org/wiki/Network_address_translation “] network address translation [/ url]” or “NAT”.[b] Please consider NAT as the telephone extension number. There is only one telephone number in the office telephone, but there are many telephone with the extension number. [/ b] Your [url = “http://en.wikipedia.org/wiki/Router”%5D router [/ b]
On request, the router uses its local NAT IP address to forward the request to the appropriate local machine.
You can easily know if your IP address is either NAT (local) IP or external (Internet) IP.
Private IP address reservation
10.0.0.0 – 10.255.255.255 – Class A
172.16.0.0 – 172.31.255.255 – Class B
192.168.0.0 to 192.168.255.255 – Class C
If your IP is in that range, it seems to be a private NAT IP. These IP address ranges can not be used for [url = “http://en.wikipedia.org/wiki/Internet_service_provider”%5D Internet service provider [/ url] or “ISP”.
