Tunnel proxy ip principle: in-depth analysis of its working mechanism and application program

How the hell does this thing spin?

To put it bluntly, a tunnel agent is like a courier relay station. When you buy something online, the seller doesn't send it directly to you, but first to a rookie station, right? That's what a tunnel broker does, except that it transmits web requests. For example, if you want to visit a certain website, the request goes to the proxy server first to turn around, change the vest (IP address) and then go to knock on the door.

Here's the kicker. The biggest difference between this stuff and a regular agent is thatauto-IP change. Ordinary proxies have to be changed manually, which is as troublesome as changing clothes. Tunnel proxies have their own IP pools and randomly grab a new IP for each request, so the website won't recognize who you are.

The three axes hidden behind the scenes

1. Request a relay race: your device → tunnel server → target website, the whole process encrypted like military communications. For example, if you use curl to access it, it looks like this:

curl --proxy socks5://ipipgo.com:1080 https://target-site.com

2. IP face-liftingThe TK line of ipipgo can be switched in milliseconds, which is especially useful when collecting data.

3. Traffic camouflage：把代理流量伪装成正常HTTPS流量，就像把威士忌装进可乐罐。这样防火代理根本嗅不出异常，特别适合需要长期稳定连接的场景

These are the scenarios you can definitely use

Hands On

Extracting proxies with ipipgo's API in three steps:

 Python Example
import requests

proxy = {
   'http': 'http://用户名:密码@gateway.ipipgo.com:9020',
   'https': 'http://用户名:密码@gateway.ipipgo.com:9020'
}

resp = requests.get('destination URL', proxies=proxy)
print(resp.text)

When you encounter a site with a lot of CAPTCHA, remember to add random waiting time in the code, don't swipe like a robot.

Guidelines on demining of common problems

Q: Why the sudden slowdown?
A: 80% of the IP pool with too hard, cut to the exclusive static package immediately see the effect. ipipgo's exclusive IP as low as 35 dollars a month, cheaper than drinking milk tea.

Q: How to avoid IP blocking?
A: Residential IPs are much more reliable than server room IPs. ipipgo's dynamic residential packages with real-life device fingerprints are hidden in depth

Q: What should I do if I can't connect to the client?
A: First check the whitelist settings, enterprise-level users remember to open sub-account privileges. If you can't figure it out, go directly to their technical customer service, the response speed is faster than a delivery boy!

Why ipipgo?

The dynamic residential IP of this house is really cow, 200+ countries in the world to choose. The cheapest package 7 more than 1 G, do crawl brother know how fragrant this price. The key is their TK line, specifically optimized for the e-commerce platform, more than ten times more stable than ordinary agents.

If you need to keep your number for a long time, you can go directly to the static residence package. 35 dollars to buy a fixed IP, and rent a house like stable. Recently, they also came out with a cloud server package program, agent + server a dragon, save worry to grandma's house.

Finally, a cold knowledge: remember to turn off the browser location function when you use the proxy, some sites will catch both IP and geographic location, revealing the secret will be a waste of effort!
