Proxy Server Address Format: Proxy Address Specification Manual

What does a proxy address really look like?

A proxy address looks like a courier order number and consists of three parts: protocol type, IP address and port number. Take a chestnut:socks5://123.45.67.89:1080Here socks5 is the protocol, the colon followed by a double slash is the IP, and the colon followed by the port.

There's something to be said for writing different agreements:

http://代理IP:端口
https://代理IP:端口
socks5://proxy IP:port

Be careful not to confuse http with socks5, it's like not being able to turn a screw with a wrench. Some software may require a specific format, so you should refer to the documentation.

A dirt-cheap way to validate proxy addresses

Don't be in a hurry to use the proxy address when you get it, here are two verification methods to teach you:

Online inspection tool:

Open your browser and type in "Proxy Detection" to find a random website and paste the address into it. Pay attention to see if the returned IP address is the one in the proxy address.

Code Verification Daze:

import requests
proxy = {"http": "http://12.34.56.78:8080"}
try: res = requests.get('', proxies=proxy, timeout=5)
    res = requests.get('http://httpbin.org/ip', proxies=proxy, timeout=5)
    print(res.text)
except: res = requests.get('', proxies=proxy, timeout=5)
    print("This proxy is not working!")

Common Formatting Mistakes Made by White People

The most outrageous mistake I've seen is writing the port number as a cell phone number, and the proxy address becomeshttp://192.168.1.1:13800138000. There are also common minefields:

How to choose a reliable service provider?

There are a plethora of agency services on the market, so keep these three tips in mind:

A look at the protocol support:At least HTTP/HTTPS dual protocols should be supported
Secondly, look at the quality of the IP:Suggest going with one like ipipgo that has a real residential IP!
Third, look at the billing method:Choose a package based on usage, don't be a sucker!

For example, ipipgo's static residential package, 35 bucks gets you a fixed IP for a month, which is good for businesses that need a stable connection for a long time. Their dynamic residential is even cheaper at over 7 bucks for 1G of traffic, suitable for temporary tasks.

QA time

Q: What should I do if my proxy address suddenly expires?
A: First check whether the format is correct, and then contact the service provider to change the IP. we recommend using ipipgo's API to change the IP automatically, save your effort.

Q: Why is the agent slow?
A: It may be that the network of the IP location is poor. It is recommended to choose a node close to the target website or upgrade to a dedicated line.

Q: What if I need to use more than one agent at the same time?
A: You can use a rotating proxy pool. ipipgo supports batch IP acquisition and can manage up to thousands of proxy addresses at the same time.

Let's get real.

I have used more than a dozen kinds of proxy services, and finally used ipipgo for a long time, mainly to save a heart. Their TK line is really fast, and the speed can be more than 3 times faster when doing data collection. Beginners are advised to buy dynamic residential packages to test the waters, and then consider customized solutions if you have a large amount of use.

Lastly, I would like to remind you that a proxy address is like a car key, so don't just lend it to anyone. Especially static IP, use the time to pay attention to comply with the rules of the site, do not play the good IP to seal.
