Distributed Crawler IP Pooling Scheme: Architectural Design for Large-Scale Data Collection

When the crawler meets the anti-crawl wall: IP pool is the hard truth

Have done data collection of old iron understand, stand-alone crawler is like a canoe out to sea, encountered the wind and waves said overturned. Anti-crawl system is now as fine as a monkey, ordinary proxy IP can not be used for half an hour into the blacklist. At this time we have to engage in distributed crawler IP pool, to put it bluntly is the formation of an "IP fleet", so that the target site can not feel our reality.

IP Pool Architecture Triple Axe

Let's start with the core configuration, you have to get three systems to fight the war:IP grabberresponsible for woolgathering from service providers like ipipgo.Validation Center24-hour physical examination of IP healthiness.movement control centerPlay with the most flowers and engage in smart allocation based on business needs.

 Simple scheduling pseudo-code example
def Assign IP(task type).
    if need long term session: if need long term session: if need long term session: if need long term session: if need long term session.
        Get an IP from the ipipgo static pool that is as stable as an old dog.
    elif need high frequency switching: call ipipgo dynamic IP
        Call ipipgo dynamic IP rotation mode.
    else.
        Randomly assign residential proxies

The combination of movement and static is the way to go.

ipipgo's dynamic and static homes have to go together, like stir-frying vegetables to master the heat:

Anti-blocking Practical Tips

1. don't use free proxies, that stuff is more unreliable than papier-mâché. ipipgo's dynamic IP pool has 90 million+ residential IPs, and the probability of being blocked is lower than winning the lottery.

2. Remember the settingsRequest Cooling TimeDon't send requests like a starving ghost, with ipipgo's intelligent rotation interval, let the target site think it's a real person!

3. Focused web siteCity-level positioningFunctions, such as crawling Shanghai local information, lock ipipgo Shanghai regional IP, to avoid abnormal access to foreign places

question-and-answer session

Q: How much IP volume do I need for the IP pool to be sufficient?
A: 500-1000 dynamic IPs are enough for common projects, like ipipgo's dynamic residential packages that automatically replenish new IPs every hour, and enterprise-level businesses are recommended to choose their customized solutions.

Q: How do I break Cloudflare validation when I encounter it?
A: Go on ipipgo's static residential IP with browser fingerprinting camouflage. Their ISP native IP over verification success rate is 8 times higher than normal proxies

Q: What should I do if data collection is always interrupted?
A: Check the survival rate of the IP pool. ipipgo's verification interface can return the IP availability status in real time. It is recommended to turn on their intelligent fusion mechanism to automatically isolate faulty nodes

The Doorway to Choosing a Package

ipipgo's dynamic residences are divided into standard and enterprise versions, see here for the main differences:

• Standard Edition: suitable for startup teams, support pay-per-use without waste
• Enterprise Edition: with exclusive API channels and priority scheduling, a must for multi-million data collection.

If you are doing a long term monitoring program, remember to pair it with a static IP package. Their 500,000+ static IP pool is solid for raising numbers or maintaining sessions.

The last nagging sentence, engaged in distributed crawlers do not toss their own proxy pool, professional things to ipipgo such service providers. Their intelligent route optimization can pressure the delay to 2ms or less, than self-built proxy pool is not a half a star.
