TIPS: how to hide your IP address on the Internet (1)

In some occasions (such as when posting a forum), some netizens want to hide their IP addresses to avoid IP addresses being written down. For security reasons, they do not want others to know their IP Addresses During QQ chat ...... But how can I hide my IP address on the Internet? The method is simple, that is, using the proxy server!

I. Proxy Server Type

The proxy server is actually a server between the browser and the website you want to access. When you browse the Internet through the proxy server, the browser first sends a request to the proxy server instead of directly retrieving the webpage from the Web server, and then send it to your browser. So when you use a proxy server to browse, the website records the proxy server address and does not record your IP address! Currently there are many proxy servers on the Internet, most of which are free of charge. Proxy servers can be divided into the following types:

1. Security Classification Based on request information

Proxy servers include super anonymous proxies, normal anonymous proxies, and transparent proxies.

The super anonymous proxy can be classified into level 1 and level 2 anonymous proxies. If you use a level-1 anonymous proxy to connect to a server, the server-side network administrator will not know that you have used the proxy, and your IP address cannot be found! Because this proxy server is a real anonymous proxy, it will not change your request fields (Message), making the server end look like a real client browser accessing it. At present, there are very few first-level anonymous proxies on the Internet. Such Proxy Server resources are very precious!

As for the second-level anonymous proxy, the security of the second-level anonymous proxy is not as good as that of the first-level anonymous proxy. The second-level anonymous proxy is used to access the Internet. Although the server's network administrator cannot find your IP address, it knows that you have used the proxy!

Normal anonymous proxy includes three-level and four-level anonymous proxy. This type of proxy server can also hide your real IP address, but it will change your request fields, so the server will know that you have used the proxy! However, this proxy will strip some of your information (like the stealth mode of the firewall), so that the server side cannot detect your operating system version and browser version.

Transparent proxy (five-level anonymous proxy): This proxy will adapt your request fields (Message) and send your real IP address. Therefore, if you use this proxy to access the Internet, you cannot hide your IP address.

2. Classification by proxy server usage

Proxy servers can be divided into the following types:

Http proxy (ports are generally 80, 8080, 3128, and 50050): The main proxy browser accesses the webpage.

SSL Proxy (Standard port 443): supports http proxy with a maximum encryption strength of 128 bits. It can be used as a proxy for accessing encrypted websites.

FTP Proxy (port 21 and 2121): the ftp software on the proxy client accesses the ftp server.

Telnet proxy (port 23): telnet of the proxy communication machine for remote control.

POP3 proxy (port 110): the mail software on the proxy client uses pop3 to receive mails.

Socks proxy (Standard port 1080): It is an all-around proxy that supports multiple protocols, including http, ftp, and other types of requests. Socks 4 supports socks 4 and socks 5. socks 4 only supports TCP protocol, socks 5 supports TCP/UDP protocol, and various authentication mechanisms.

In addition, there are also TUNNEL proxy, document proxy, CERNET proxy, Ssso proxy, and Flat proxy. We will not discuss them here.
