What is IP address?

IP address (Internet Protocol Address), or briefly IP Address (IP Address) is a numerical address that each of the devices and computer connected to the computer network based on the refrence model TCP (including INTERNET) works, are allocated. Messages that other computers to send the computer along with a number sign and the network routers such as the receiver address in Mail is meant, until finally the message about the computer network interface appears.

Type of IP address:IP address version 4, Ip address address version 6

IP version four of a number 32BIT is to simply form the four sections in the numerical basis ten of -point writing that are separated (such as 199.211.45.5). This way the Nshanydhy Nqthdar Decimal call any of the four parts of a octet (Octet) called because its length 8 bits (or a B) and could be a number from 0 to 255. After 2 to 32 can have a different address.

Basically any 32-bit IP address is divided into two parts: a prefix and a suffix. These two levels in order to create an efficient routing method has been developed. Address prefix, the network computer is connected to it defines (Network) extension, while a computer on the network to specify uniquely (host). Ie, any network on the Internet that a unique value as the network number is known, is dedicated. No network as a prefix in the address of each computer is connected to the network appears. In addition to any computer on a network, an extension is allocated uniquely address.

Each full address including a prefix and a suffix is so unique that they are allocated, so the first property is guaranteed. If two computers connected to two different networks, they will have different prefixes Nshanyhayshan. But if two computers are connected to a network, with extensions Nshanyhayshan will be different
