How does the website remember the ip address of the computer and surf the Internet?

Website to get our information (ip, time, city, etc. ) through cookies. Cookies are introduced as follows:

1, Cookies are a technology that allows a website server to store a small amount of data in the client's hard disk or memory, or read data from the client's hard disk.

2.Cookies are very small text files, which are put on your hard disk by the Web server when you browse a website. It can record your user ID, password, web pages you visited, stay time and other information. When you come to the website again, the website can read Cookies and get your relevant information, so you can take corresponding actions, such as displaying a welcome slogan on the page, or allowing you to log in directly without entering an ID or password. It can be regarded as your ID card in essence.

3.Cookies cannot be executed as code, nor can they spread viruses. They are proprietary to you and can only be read by the server that provides them. The saved pieces of information are stored in the form of "name-value pair", which is just a named piece of data. A website can only get the information it puts on your computer, it can't get the information from other Cookies, and it can't get anything else on your computer.

4. Most of the contents in 4.Cookies are encrypted, so the average user looks like a meaningless alphanumeric combination, and only the CGI processor of the server knows their true meaning.
