Correct format of ip address
Correct format of IP address: 192.168.0.1; IP address is used to give a number to a computer on the Internet.

The Internet Council defines five types of IP addresses to fit different capacity networks, namely, Class A to Class E. IP addresses are usually expressed as (a.b.c.d) in “dotted decimal”, where a, b, c, and d are decimal integers between 0 and 255. It is actually 32-bit binary (01100100.00000100.00000101.00000110).
Class D addresses are used for multipoint broadcasting. The first byte of a Class D IP address begins with “1110”, which is a reserved address. It does not point to a specific network, and is currently used in Multicast, where it is used to address a group of computers at a time in the range 126.96.36.199-188.8.131.52.
Class E IP addresses, which begin with “1111”, are reserved for future use. ” are reserved for future use, and Class E addresses are reserved for experimentation and development only.

Interpretation: The protocol for interconnecting networks.
Syntax: IP, in full: Internet Protocol address, is an IP address, meaning a numerical label assigned to a device that uses the Internet protocol for users to access the Internet.
It tracks system IP addresses, netmasks, routes, and gateway information.
What are IPs and client IPs?
The IP address identifies a unique host on the Internet, so it is unique, so you can be sure not to “go to the wrong door”.
The server is already the “door” to the network because of Baxter, and is the IP of the server, which is artificially fixed to make sure that the door does not run.
The client IP is its own IP, which may not be the same every time you go online, but the door through which you can access the server is a fixed “door”.
Fixed IP (i.e., static IP): Fixed IP address is a long-term fixed IP address assigned to a computer to use, generally a special server with a fixed IP address. Generally, computers that use a dedicated line to connect to the Internet only have a fixed Internet IP address, which requires a more expensive fee.
Dynamic IP: Access to computers via modem, ISDN, broadband, cable broadband, broadband, and other means of accessing the Internet is not the same every time an Internet IP address is assigned, which is a dynamic allocation of temporary IP addresses by the ISP.
Because IP address resources are very valuable, most users access the Internet through dynamic IP addresses. The average person does not need to know the dynamic IP address, this is done automatically by the computer system.
Public broadcasting is the responsibility of the Internet Information Center. These IP addresses are assigned to organizations that register and apply for internic. It provides direct access to the internet.
