An Internet Protocol (IP) address is a numerical label that is assigned to devices on a computer network, which uses the Internet Protocol for communication between its nodes. The architecture of an IP address is based on the network structure. An IP address consists of the network ID and host ID.
You need to allocate IP addresses for the hosts on an IP network. To connect a computer to the Internet, you need to apply to the Internet Service Provider (ISP) for an IP address.
An IP address is a 32-bit binary number. To help users to recognize and remember IP addresses, IP addresses are expressed in dotted decimal notation. In dotted decimal notation, an IP address consists of four dotted decimal integers. Each decimal integer corresponds to a byte. For example, the binary IP address of the host A is 00001010 00000001 00000001 00000010; the decimal IP address of the host A is 10.1.1.2.
An IP address consists of the following fields:
Network ID field (net-id): It is used to distinguish networks. The bits of the net-ID are called the class field (or class bits). These bits are used to distinguish the IP address class.
Host ID field (host-id): It is used to distinguish different hosts on the network.
The network ID field identifies a network, and the host ID field identifies a connection of the network device on the network. If multiple network devices have the same network ID, they reside at the same network regardless of their locations. That is, whether multiple network devices on a public network reside at the same network does not depend on their locations.
