Crawler Proxy Pool Purchase: A Guide to Building and Maintaining an Efficient and Stable IP Resource Pool

Why do you have to use a proxy pool for crawlers? Read it and save three years!

Brothers just entering the industry always think that just grab a few free IP can start, the result is either hammered by the anti-climbing mechanism, or data capture incomplete. This is like chopping a tree with a chopper - the strength is not less, the effect is not very good.The core of the existence of the proxy pool on three points: anti-banning, stability, and improve efficiencyThis is the first time I've ever seen a website with a high frequency of visits. Especially now that the site are installed intelligent wind control, the same IP high frequency access directly cool.

To cite a real case: a price comparison platform team, using their own office network to capture data, the results of the next day, the entire company's IP segment was the target site black, even the normal business is affected. This is a typical failure to do a good jobIP resource isolationThe consequences of the

Four tips to teach you to pick the right proxy IP service provider

The market is a mixed bag of agency services, so keep these hard indicators in mind:
①IP Purity(Don't use those spammy IPs that get blacked out all over the net)
②Protocol Support(must be socks5/http compatible at least)
③Response speed(Pass for more than 2 seconds)
④After-sales response(Anyone who can't be found is a pit)

It's important to mentionipipgos unique skill - their home residential IP library covers more than 240 countries with real home network environment, which is more difficult to be recognized than server room IP. Especially when doing domestic data collection, they can automatically match the characteristics of local residents' Internet access, an advantage that is really rare in the industry.

Hands-on building of highly available proxy pools

Don't be intimidated by the fancy architecture diagrams, the core process is just five steps:
1. Selection of service providers (e.g. ipipgo)
2. Configure API automatic extraction
3. Setting up the authentication module (periodic checking of IP availability)
4. Dynamic scheduling algorithms (IP allocation based on service)
5. Abnormal monitoring alarms

Here's the kicker.dynamic schedulingThe piece. It is recommended that the IP pool be divided into three groups:
- Hot Pools: Quality IPs in High Frequency Rotation
- Warm pool: spare replacement
- Cold pool: Failure isolation zone
This ensures resource utilization and fast switching of failed nodes.

The Three Minefields of Maintaining a Proxy Pool

Seen too many people fall on their asses here:
① hate to change IPs: Some invalid IPs are still occupying space.
② brainless pile of numbers: Actually, 200 quality IPs work better than 2,000 spam IPs.
(iii) Ignore protocol adaptationFor example, a scenario that requires socks5 uses an http proxy.

There's a tricky trick - use ipipgo's smart routing feature to automatically select the optimal locale and protocol type based on the target site. They can see the success rate of each IP in real time in the background, which helps a lot in tuning.

A must-see hands-on Q&A for beginners

Q: What should I do if I always encounter CAPTCHA?
A: Check the IP purity first, then adjust the request frequency. It is recommended to use ipipgo's dynamic residential IP with browser fingerprinting simulation

Q: How much capacity do I need for the proxy pool?
A: 200-500 IPs are enough for 50,000 requests or less per day. Focus onIP multiplexing ratioInstead of total

Q: What should I do if a large number of IPs suddenly fail?
A: Start the backup channel immediately and check the service provider API status. Those with disaster recovery mechanisms like ipipgo will automatically switch node pools

Finally, a big truth: the proxy pool is not a once-and-for-all thing, you have to continue to optimize. Choose the right service provider can save 80% trouble, the rest is based on business characteristics of fine-tuning. Don't always think of whoring free resources, professional things to professional people, efficiency gains are absolutely cost-effective.
