Because of this unique address, when users operate on networked computers, they can effectively and conveniently select the objects they want from thousands of computers in Qian Qian.
1.IP address to realize the interconnection of different hardware structures, different operating systems and different network systems around the world. On the Internet, each node relies on a unique IP address to distinguish and contact each other.
2.IP address is a 32-bit binary address, which consists of four 8-bit fields, each separated by a dot to identify the TCP/IP host.
3. Each IP address contains two parts: network ID and host ID. The network ID identifies all hosts on the same physical network, and the host ID identifies each host on the physical network, so each computer on the whole Internet is identified by its own unique IP address.
4.IP address forms the foundation of the whole Internet, which is so important that every computer connected to the Internet has no right to set its own IP address. There is a unified organization-iana, which is responsible for assigning unique network IDs to the organizations applying, so that organizations can register in their own networks, just as a unit has no right to decide the street name and house number of its own city, but can decide its own office number.
Extended data
Every host on the Internet has a unique IP address. IP protocol uses this address to transfer information between hosts, which is the basis of Internet operation. The IP address is 32 bits in length (* * * has two 32 IP addresses), and it is divided into 4 segments, each with 8 bits, expressed by decimal digits, and each segment ranges from 0 to 255, and each segment is separated by a period.
For example,159.226.1.1. IP address can be regarded as network identification number and host identification number, so IP address can be divided into two parts, one is network address and the other is host address. IP addresses are classified into categories A, B, C, D and E5, and the applicable types are: large-scale networks; Medium-sized network; Small network; Multiple destination addresses; Spare. Commonly used are b and C.
