Pure proxy: non-polluting IP pool construction and data collection practical teaching

First, why is the proxy IP pool always played?

The biggest headache for those who are engaged in data collection is that their IPs are blacked out. You have been trying to write a crawler script, running not two hours on the break, the system prompts "too frequent visits". At this time it is time to offer the proxy IP pool this magic weapon, but many people directly take the public proxy to pour in, the results are worse than not using ---Sequestration rate increases rather than decreasesThe

The root of the problem lies in the quality of IP. It is like going to the market to buy fish, the pool is mixed with dead and sick fish, the dishes can be delicious? The free agents on the market are like these sick fish, which have long been repeatedly ravaged by various reptiles. Some IPs have even been labeled as malicious nodes, and accessing websites with such IPs is like going to the bank with ex-convicts to do business, so can we not be vigilant?

Second, pure IP pool building four steps

Step 1: Choose the right water source
Don't look for ingredients in the garbage. We recommend using ipipgo's residential IP resources, their IPs are from real home broadband, like live fish directly from the fishpond. more than 90 million IPs are distributed in more than 240 regions, support for dynamic static two modes. Dynamic IP is suitable for scenes that require frequent switching, and static IP is more stable for services that require login state.

Step 2: Pipe Diversion
Don't put your eggs in one basket. It is recommended to divide IP pools by business type, for example:
- Dedicated pool for account registration
- Dedicated pool for data acquisition
- Authentication Login Dedicated Pool
用ipipgo的API可以按国家、运营商、代理协议等参数精准筛选IP，支持socks5/http/https多协议，像给不同菜品准备专用砧板。

Third, the actual collection of anti-blocking skills

Tell a real case: an e-commerce platform detects 500 abnormal IP logins per hour. We configured such a program for the customer:
1. Dynamic residential IP polling with ipipgo
2. Randomization of User-Agent per request
3. 请求间隔设置2-8秒随机
As a result, it ran continuously for 72 hours with zero blocking, and the collection success rate soared from 37% to 92%.

Here's the key point.anthropomorphize behavior. Just like checking out in line at the grocery store, normal people don't put every item on the conveyor belt at precisely 3 second intervals. It's safer to include irregular operations instead.

IV. Guidelines for demining common pitfalls

Q：Why is it still blocked even though I've used a proxy?
A: It is 80% that the cookies are not cleaned up. Some crawler frameworks will automatically bring local environment parameters, remember to reset the browser fingerprint every time you switch IP.

Q: What should I do if my domestic website is particularly slow to access?
A：试试ipipgo的智能路由功能。他们家的节点支持自动选择最优线路，比手动指定地区快得多。之前有个客户采集东南亚电商数据，直接从800ms降到120ms。

V. IP pool maintenance cold knowledge

Many people don't realize that they have to regularlyPhasing out old IPs. Even if the quality of the residential IP is good, it will be targeted by the website if you use it for three months continuously. It is recommended to replace the IP reserve of 30% every month, and using ipipgo's API to get fresh IPs is like changing the water to the fish pond regularly.

One last reminder: don't mix proxies from different service providers in your IP pool. The quality of each IP varies, just like you can't raise seafood and river food in the same pool. Focus on using ipipgo such as professional service providers, in order to ensure that the water quality of the entire pool is pure.
