Dynamic l2tp proxy: Dynamic L2TP proxy rotation scheme

What exactly is the use of dynamic l2tp proxies?

A lot of data collection friends have encountered this situation: the target site suddenly blocked your IP. dynamic l2tp proxy at this time is like a magician who will change face, each connection can change a "face". To put it bluntly, it is by constantly switching the temporary IP address assigned by the operator, so that the website will treat you as an ordinary user.

Traditional static proxy is like using the same key to open the lock, dynamic proxy is like carrying a universal locksmith. Especially for long-term data monitoring business, with this program can effectively avoid the anti-climbing mechanism. To cite a chestnut, an e-commerce platform price tracking project, with a fixed IP crawl half an hour to be blocked, replaced with dynamic polling after three days of stable run.

Hands-on with a dynamic rotation system

Here is an example of ipipgo's Dynamic Residential (Standard) package. First, generate an API key on the official website to get a pool of proxy server addresses. Note that you have to choose a server node that supports the L2TP protocol, this can be filtered in the control panel.

import requests
import time

def get_new_ip(): api_url = "": api_url = "new_ip
    api_url = "https://api.ipipgo.com/dynamic"
    params = {
        "key": "Your API key",
        "protocol": "l2tp",
        "count": 1
    }
    response = requests.get(api_url, params=params)
    return response.json()['data'][0]

This Python code automatically obtains a new IP every hour, remember to set the timed task to a random interval, don't switch the whole point on time easily recognized. It is recommended to randomize the value between 55-65 minutes to mimic the rhythm of a real person's operation.

Avoid five common potholes

The easiest place for a novice to fall:

1. Switching too oftenAlthough dynamic proxies emphasize flexibility, changing IPs for 30 seconds will trigger wind control. It is recommended to adjust according to the business scenarios, and keep 30-60 minutes/time for ordinary web crawling is enough.
2. Forgetting to clear cookies: Changing IP without cleaning browser fingerprints is the same as changing the soup, remember to reset the session every time you switch!
3. Protocol mismatch: Some old systems only support PPTP, now the mainstream are using L2TP/IPSec, encryption is more secure!
4. Geographic selection compulsionDon't stick to a certain region's IP pool, mix it with neighboring regions for better results!
5. Neglect of traffic monitoring: Dynamic agents are billed by volume, it is recommended to set up a usage warning in the background, so as not to let the abnormal traffic burn money!

What's good about the ipipgo program?

After comparing several service providers on the market, his family has three masterpieces:

Especially theircross-border rail lineWhen doing cross-border e-commerce data acquisition, it can simulate the online environment of real overseas users. The last time I helped a customer to do exchange rate comparison project, the regular proxy is always recognized, after changing to TK line, the success rate of data acquisition soared from 47% to 89%.

Common QA for white people

Q: Will dynamic proxies be slower than static ones?
A：主要看线路质量，ipipgo的专线节点控制在200ms内，普通网页访问感觉不出差别。如果是大文件传输，建议用他们的独享静态套餐

Q: What should I do if I keep getting the message of verification failure when switching?
A: Ninety percent is that the account password is not synchronized and updated. Dynamic proxy every time you get a new IP, the authentication information will also change, remember to use the latest credentials returned by the API!

Q: Can I log in at more than one place with one account?
A: The dynamic package supports 3 devices online at the same time, and the enterprise version can be increased to 10. If you need more terminals, look for customer service to open the session concurrent privileges

Q: What should I do if I can't connect to the IP?
A: first ping the server address, if the timeout on the user center to submit the faulty node. ipipgo promised to repair or replace the new node within 2 hours, do not waste time on their own folding!

As a final note, don't just look at the unit price when choosing a package. Although Dynamic Residential (Enterprise) is a bit more expensive, it comes with request retry and automatic route optimization, which makes it more cost-effective in the long run. Beginners are advised to take the standard version of the test, run smoothly before upgrading is not too late.
