What is IP Address?

In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-bit number that identifies each sender or receiver of information that is sent in packets across the Internet. The IP address is usually expressed as four decimal numbers, each representing eight bits, separated by periods. This is sometimes known as the dot address and, more technically, as dotted quad notation. For example, 127.0.0.1 could be an IP address.

The IP Address can be divided into following categories:


  • Class A IP address ranges are for large networks with many devices (supports 16 million hosts on each of 126 networks). The first octet starts from 1 to 126. • Class B IP address ranges are for medium-sized networks (supports 65,000 hosts on each of 16,000 networks). The first octet starts from 128 to 191. 
  • Class C IP address ranges are for small networks (supports 254 hosts on each of 2 million networks ). The first octet starts from 192 to 223. 
  • Class D IP address ranges are multicast addresses. The first octet starts with 224. 
  • Class E IP address with the first octet of 225 is used for experimental purposes only. 
  • The IP address 127.0.0.1 is used as the loopback address. This means that it is used by the host computer to send a message back to itself. It is commonly used for troubleshooting and network testing.

  1. An IP(Internet Protocol) address is a numerical label that is assigned to a device (eg. computer, printer etc...) which is used in the Internet Protocol communication. The format of an IP address is a 32-bit numeric address which is written as four numbers separated by periods(.). Each number can be zero to 255. For example, 1.160.10.240 could be an IP address. An IP address can be static or dynamic. A static IP address will never be changed and it is a permanent Internet address. But a dynamic IP address is a temporary address that is assigned each time a computer or device accesses the Internet. To know network IP address visit the site Ip-Details.com .
