Distributed IP Rotation System Source Code Interpretation

How the hell does this thing spin?

The old iron who has engaged in the crawler all understand that the IP is blocked is as difficult as choking on food. Distributed IP rotation system is, to put it bluntlyInstalled an automatic armor changer on the program.The first thing you need to do is to open an unlimited number of resurrection hangs, as if you were playing a game. Let's take apart the source code to see, the core of the three major pieces:

As a chestnut, there's a tawdry operation in ipipgo's rotation system--Dynamic weighting. It's like scoring IPs, the ones that are responsive do more work, and the ones that are laggy get kicked out of the group chat. In the source code, you can see that they use a mechanism called "hot replacement", when the IP change the business is completely uninterrupted.

Hands-on look at the source code arcana

Peel back the kernel of the rotation system and focus on these two files:

ip_pool.py This file governs the "life and death" of IPs, and has aHeartbeat DetectionThe function is especially practical. Automatically ping every 5 minutes, timeout IP directly thrown into the dark room. ipipgo added black technology in this piece, can automatically adjust the detection frequency according to the type of business.

scheduler.py The core battleground of scheduling algorithms. Don't look at the code on a hundred lines, which hides the big questions of intelligent routing. For example, this judgment logic:

if response time > 2 seconds.
    Automatic downgrade
elif Failures > 3.
    Replace immediately
else.
    Weighted assignment

Why did you choose ipipgo as your backer?

Maintain your own IP pool? Don't even think about it! Seen too many people fall into these pits below:

• The IP just expired. It's like a firecracker.
• Carrier Restrictions Screw Up
• Not enough anonymity to be recognized by the site

The killer feature of ipipgo is thatThree-layer filtering mechanism, their IP resources go through:

1. Operator-level screening
2. Business Scenario Adaptation
3. Real-time quality monitoring

I have found that with his IP, the success rate of requests can beFrom 50% to 92%.The effect is immediate, especially in high concurrency scenarios.

Practical QA Giveaway

Q: What should I do if my IP suddenly fails?
A: API support for ipipgoAutomatic compensation for failureIf you want to set the retry parameter, just add it when you call it. It is recommended to set 3 retries with an interval of not less than 2 seconds.

Q: How do I judge the quality of the agent?
A: Remember these three indicators:
1. Response speed ≤1.5 seconds
2. Success rate ≥95%
3. Level of anonymity High level

Q: What is the appropriate frequency of rotation?
A: Look at the type of business:
- Normal collection: 5-10 minutes for a new wave
- High-frequency operation: change every minute
- Important business: ipipgo's recommendedsmart modeThe system automatically learns the optimal rhythm

In the end, distributed IP rotation is not to build rockets, the key to choose the right weapon. Next time you see the site anti-climbing do not iron, try ipipgo rotation program, guaranteed to open the door to a new world. Code this thing just look at not hands can not, it is recommended to take their test interface to practice, anyway, the free quota is enough to toss.
