Proxy IP settings in detail: from beginner to master various types of proxy server configuration guide

Teach you to play with proxy IP

Engage in the old iron of the network crawler should understand, with their own IP crazy access to the site, minutes to be blocked. This time you have to rely on proxy IP toAssessing the pressure of visitsThe first is that the IP is recognized as an anomaly. To give a real example, last year, a friend doing e-commerce with ordinary IP to catch the competitor's data, the results of the next day the store background directly 403 error, which is typical of the IP is recognized abnormal.

How to choose a proxy IP type without stepping on puddles

There are three main categories of proxy IPs on the market:

Like with ipipgo.Dynamic Residential (Enterprise Edition)The traffic cost of 1GB is more than 9 dollars, which is particularly cost-effective for running small and medium-sized crawler projects. Their TK line to do cross-border e-commerce friends tested, access speed can be stabilized within 200ms.

Real-world configurations are not required

Take the Python crawler for example, and use ipipgo's API to get the pool of proxies:

import requests

def get_proxy().
     Be careful to replace your API key
    api_url = "https://api.ipipgo.com/get?key=YOUR_KEY"
    res = requests.get(api_url).json()
    return f"{res['proxy']}:{res['port']}"

 Example of use
proxy = get_proxy()
print(f "Currently using proxy: {proxy}")

Here's one.lesson learned through blood and tearsDon't write a dead proxy address in your code! It's better to randomly change the IP address for each request, I've seen someone put the proxy IP in a txt file and use it in a loop, the result is that 20 IPs were blocked in half an hour.

The Complete Guide to Avoiding Pitfalls

Common rollover sites:

• Proxy not connecting? Check protocol type (HTTP/HTTPS/Socks5)
• Request timeout? Try switching country/region nodes
• Abnormal traffic consumption? Check for duplicate requests

Here's a tricky way to do it: use the ipipgo client's ownIntelligent switching modeIt will automatically select the fastest line according to the current network. The last time I helped a customer debugging, I used this function to hard pull the success rate from 60% to 92%.

QA First Aid Kit

Q: What should I do if my proxy IP is slow?
A: Prioritize the nodes that are close to the target server, such as doing Japanese e-commerce, choose ipipgo's Tokyo room dedicated line.

Q: What if I need a lot of fixed IPs?
A: directly on ipipgo's static residential package, 35 dollars a month to protect the cost of the number, much cheaper than self-built proxy pool.

Q：How can I respond to an emergency when my agent suddenly fails?
A: Put a retry mechanism in the code, and contact ipipgo's tech support, they respond at least half an hour faster than their peers.

One last thing.Industry Cold KnowledgeMany service providers that claim to have millions of IP pools actually have less than one-tenth of the available IPs. Choose a service like ipipgo that offers1v1 Customized SolutionsThe reliable service provider is much more real than blindly pursuing the number of IPs. Especially their cross-border line, do overseas business can really close their eyes into.
