Where to set proxy ip? Browser, system, and application level 3 configurations explained in detail

Browser Setup Proxy IP: 3 Minutes to Get Started Fast

The most commonly encountered scenario is that the browser needs to change the IP address to access the Internet, take Chrome and Firefox as an example. Open Chrome Settings → Advanced → System → Open Proxy Settings, which will bring up the system's Internet Properties (don't worry, the system settings will be discussed later).Focus on the browser's own configurationLike Firefox in the "General ¡ú Network Settings" can set up a separate proxy, this and the system settings are separate, many people are easy to confuse.

For example, when you use ipipgo's Dynamic Residential Proxy, put socks5://us.ipipgo.com:30001 in Firefox, and remember to check the box "Use this proxy for all protocols". There is a pitfall to be aware of here:Browser settings are prioritized over system settings, if both sides are configured, the browser says so.

// Example of setting up the Python requests library, which is commonly used by crawlers.
import requests
proxies = {
    'http': 'socks5://user:pass@us.ipipgo.com:30001',
    'https': 'socks5://user:pass@us.ipipgo.com:30001'
}
response = requests.get('http://example.com', proxies=proxies)

System-level agent setup: one trick for all software

Windows users press Win+R and type control to open the Control Panel, look for "Network and Internet→Proxy", the proxy set here will affect all the software that go through the system proxy.Mac userConfigure it in System Preferences→Network→Advanced→Proxy, and remember to set it up separately for WiFi and wired networks.

Here's a tutorial on how to do it: when using ipipgo's static residential proxy, you can create theOn-demand switching of configuration groups. For example, save the proxy address of the United States, Japan and Germany, and switch which country IP you need with one click. I've tested that in Win11, you can switch quickly with netsh command:

netsh winhttp set proxy proxy-server="socks=us.ipipgo.com:30001"
netsh winhttp reset proxy // clear proxy

Application-independent configuration: precise control without crosstalk

Like crawler software, data analysis tools, these, it is recommended to set up a separate proxy. In Python, for example, in addition to the requests library, using aiohttp to do asynchronous requests should pay attention to the session level proxy configuration:

async with aiohttp.ClientSession() as session.
    async with session.get(url, proxy="http://us.ipipgo.com:30002") as resp.
        print(await resp.text())

游戏玩家看这里：Steam客户端的代理在设置→网页浏览器里配置，实测用ipipgo的静态代理打美服能降60ms。不过要注意UDP protocol supportSome games require special settings, so it's a good idea to choose a proxy that supports SOCKS5.

Proxy IP Frequently Asked Questions QA

Q：Why does it still show the real IP after setting the proxy?
A: First check the proxy format, especially the protocol type (HTTP/SOCKS5 don't get confused). We recommend using ipipgo'sIP Detection Tool, which can be verified by directly visiting ip.ipipgo.com/check

Q: What should I choose between dynamic and static proxies?
A: Depends on the use of the scene! Need long-term stability (such as hanging games) choose static residential, slightly more expensive but stable as an old dog. Dynamic proxy is suitable for the need to frequently change the IP crawler business, ipipgo's dynamic packages can change new IP every minute.

最后说个冷知识：用代理IP访问自家网站时，记得在服务器防火代理里把代理IP加入白名单。特别是用ipipgo的企业版静态IP，固定地址管理起来贼方便。要是碰到啥怪问题，他们家技术客服响应速度杠杠的，亲测凌晨三点都能秒回工单。
