In the world of the Internet, the proxy server acts as a bridge between the client and the target server. It can hide the user's real IP address, provide anonymity and security. The IP address format of the proxy server, as an important part of configuring the proxy service, directly affects the normal use of the proxy function. Mastering the correct IP address format is the key to ensure the smooth operation of the proxy service.This article will explore the format of the proxy server IP address, including how to choose the proxy server IP, how to configure it, and how to achieve the best results through tools such as IP2world.1. The basic structure of the proxy server IP addressThe IP address format of the proxy server usually follows the IPv4 or IPv6 protocol. IPv4 is the most common format at present. It consists of four groups of numbers, each of which ranges from 0 to 255 and is separated by a dot (.). For example, the common IPv4 address format is `192.168.1.1`.Compared with IPv4, the IPv6 format is more complicated. It consists of eight groups of four hexadecimal numbers, each separated by a colon (:), such as `2001:0db8:85a3:0000:0000:8a2e:0370:7334`.In the configuration of proxy servers, the common writing method is usually the IPv4 format, but with the advancement of technology, IPv6 has gradually been used, especially when IP address resources are tight.2. IP format in proxy server configurationWhen you set up a proxy server, the IP address is not only used to identify the server itself, it is also related to whether the traffic can be routed correctly. The IP address configuration of the proxy server usually involves the following aspects:Static IP vs. Dynamic IPA static IP address means that the proxy server always uses a fixed IP address each time it connects to the network, while a dynamic IP may change with each connection. Static IP addresses are suitable for users who need to use the same IP address for anonymous access for a long time, while dynamic IP addresses are suitable for users who frequently change IP addresses to avoid being tracked.When using proxy services such as IP2world, static IP is more common because it provides a more stable proxy service. Dynamic IP is mostly used in large-scale proxy pools to enhance anonymity by frequently switching IP addresses.Proxy TypeThe configuration of the proxy server also involves the selection of the proxy type. Different types of proxy servers may use different IP formats. Common proxy types are:- HTTP proxy: A proxy service suitable for web browsing, mainly used to access HTTP websites, and the proxy address is usually specified in the `http://IP:port` format.- HTTPS proxy: Similar to HTTP proxy, but supports encrypted connections and uses the `https://IP:port` format.- SOCKS proxy: A more general proxy protocol that supports proxy services for multiple network protocols. The common format is `socks://IP:port`.Each proxy type has its own unique IP address format and port settings. The correct format can ensure that the proxy server works properly.3. How to correctly write the IP address of the proxy serverWhen configuring a proxy server, it is crucial to ensure the correctness of the IP address and port number. Whether it is IPv4 or IPv6 format, the configuration of the proxy server usually includes the IP address and port number. For example, when configuring an HTTP proxy, the format is `http://192.168.1.1:8080`, where `192.168.1.1` is the IP address of the proxy server, and `8080` is the proxy port number.For some services that use a proxy pool, there may be multiple IP addresses and port numbers to choose from. Usually, tools such as IP2world are used to obtain a valid proxy IP address.IP address format notes- Legality: Make sure the IP address format is correct to avoid invalid IP addresses such as `999.999.999.999`.- Port number: Proxy servers usually need to specify port numbers. Common ports include `1080` (SOCKS proxy) and `8080` (HTTP proxy).- Proxy pool: Some proxy services provide multiple IP addresses. Users can select the appropriate IP for configuration according to their needs. Through tools such as IP2world, users can quickly obtain and verify the validity and stability of IP addresses.4.

In daily network use, checking IP through a proxy server is an important skill. This can not only verify whether the proxy server is working properly, but also help users confirm whether the currently used IP has achieved anonymity. As a transit station for network access, the proxy server can replace users to directly connect to the target server, thereby hiding the real IP address. Combined with the professional proxy service provided by IP2world, users can easily switch and detect IPs, providing technical support for privacy protection and multi-region access.1. The basic principle of proxy serversA proxy server is an intermediate device located between the user and the target server. The user sends a request to the target server through the proxy server. After receiving the request, the proxy server initiates access to the target server with its own IP and passes the return result to the user.This mechanism provides users with many conveniences:1. Hide the real IP: When accessing the target website through the proxy server, the target website can only see the IP of the proxy server and cannot track the user's real IP.2. Break through access restrictions: Some websites restrict access to specific areas. The proxy server can easily bypass these restrictions by providing IP addresses in different regions.3. Improve network security: Using a proxy server can avoid directly exposing the user's real device information to a certain extent and effectively resist some malicious attacks.2.
