In today's Internet era, the use of proxy servers has become more and more common. Whether it is to protect privacy, bypass geographical restrictions, or increase network access speed, proxy servers can provide effective solutions. However, for many users, how to correctly fill in the proxy server IP and port information is still a problem. This article will delve into the basic concepts of proxy servers and how to correctly configure proxy settings in different devices and applications, especially how to fill in IP and port.1. Understand the basic concepts of proxy serversA proxy server is an intermediary that sits between the user and the target server and is responsible for forwarding the user's request and returning a response. Through a proxy, users can hide their real IP address, bypass geographical restrictions, and access specific websites or services. Proxy servers can be divided into many types, including HTTP proxy, HTTPS proxy, and SOCKS proxy, each of which has its specific uses and advantages.1. HTTP proxyHTTP proxy is mainly used to process HTTP protocol requests, suitable for browsing web pages and downloading files. It can cache web pages and increase access speed.2. HTTPS proxyHTTPS proxy is used for secure HTTPS requests, which can encrypt the communication between users and the target server and protect user privacy.3. SOCKS proxySOCKS proxy is a general proxy that can handle any type of network traffic and is suitable for scenarios that require greater flexibility, such as P2P downloads or online games.2. Definition of proxy server IP and portWhen using a proxy server, users need to fill in two important pieces of information: IP address and port number.- IP address: This is the network address of the proxy server, through which users connect to the proxy server. Each proxy server has a unique IP address.- Port number: The port number is a number used to identify a specific service. Different types of proxy services may use different port numbers. For example, HTTP proxies usually use port 80, while HTTPS proxies use port 443.3.
