IP is the abbreviation of Internet Protocol, which is a computer Web Design A protocol designed to interconnect. In the Internet, it is a set of rules that enable all computer networks connected to the Internet to communicate with each other, and stipulates the rules that computers should follow when communicating on the Internet. With IP protocol, the Internet can rapidly develop into the world's largest and open computer communication network.

Generally speaking, IP address can also be called Internet address, which is a logical address used to uniquely identify computers on the Internet. Each networked computer relies on an IP address to identify itself.

The network systems and equipment produced by various manufacturers, such as Ethernet and packet switching network, cannot communicate with each other. The main reason is that the basic unit format of the data they transmit is different. IP protocol is actually a set of protocol software composed of software programs. It converts all kinds of different unified formats into "IP packet" format, so that all kinds of computers can achieve interoperability on the Internet.

Data packet is a form of packet switching, that is, the transmitted data is segmented into "packets" and then transmitted. Each packet has a header and a message. The header contains the destination address and other contents, so that each packet can reach the destination accurately without passing the same path. Recombine at the destination to restore the original sent data.

Another important content of IP protocol is that each computer on the Internet is assigned a unique address, called "IP address". Because of this unique IP address, users can easily select the objects they need from thousands of computers when operating on networked computers.

The IP address is a 32bit address assigned to each host connected to the Internet. According to the TCP/IP protocol, IP addresses are expressed in binary form. Each IP address is 32 bits long, that is, 4 bytes. For example, an IP address in binary form is 0000101000000000000000000000001, which is very troublesome to use. For ease of use, IP addresses are often written as decimal numbers, with the symbol "." used to separate different bytes.
