Crawler Proxy Pool Purchase | Dynamic IP Pool Building and Anti-Anti-crawler Strategy

Proxy IP in the end how to choose? These pits must not step on

The biggest headache is to engage in crawlers is the IP is blocked, this time you have to rely on the proxy IP to renew their lives. There are various proxy service providers in the market, and some of them claim to have "millions of IP pools", but in reality, they may not even be able to load the web page. Selecting a proxy depends onUnderlying resource typeFor example, server room IPs are easily recognized, while residential IPs are closer to real users. Our ipipgo's residential IPs come from real home broadband, with 240+ countries and regions around the world to choose from, especially in certain hard-to-find niches, you can find the corresponding IP resources.

Be careful not to buy a shared proxy on the cheap, dozens of people use the same IP, minutes by the target site to pull the black. If you want to choose, chooseExclusive AgentThe mode, like ipipgo's dynamic residential IP automatically changes IP every time you request it, which is much less troublesome than switching manually. Here is a test method: use a proxy to access ipinfo.io and see if the returned IP type is "isp" (Internet Service Provider), which is the real residential IP.

Build your own dynamic IP pool? Hands on teaching you the whole

Dynamic IP pooling is not simply a matter of getting an IP list and calling it a day, the key toIntelligent Dispatch SystemWe can take the open source framework to make an infrastructure. We can take the open source framework to do an infrastructure, such as using Redis for IP storage, MySQL records use logs. The point is, you must set up three core mechanisms:

If you think it's too much trouble to build your own, you can directly use ipipgo's API to access the ready-made dynamic pool. Their interface supportsCustomized by business scenariosFor example, e-commerce collection with U.S. residential IP, social media collection cut to Southeast Asia IP, you can also set up automatic switching intervals, than self-built pools to save a lot of trouble.

Anti-Anti-crawl in action: making websites think you're a real person

It's not enough to have an agent. You have to learn.camouflageSome websites will detect browser fingerprints. Some sites will detect the browser fingerprint, this time remember to randomly switch User-Agent in the crawler. recommend a tart operation: use ipipgo's residential IP + corresponding time zone settings, such as using the Japanese IP will be adjusted to the time zone for the time of Tokyo, so that the access logs look more real.

Don't fight the CAPTCHA, tryThe Great Law of Flow Dilution: Spread out the requests to different IPs, with no more than 3 requests per minute from a single IP. For example, with ipipgo's dynamic IP pool, set each request to automatically replace the IP, together with the random click interval, can basically bypass the 90% anti-climbing mechanism. The actual test of an e-commerce site collection, using this method to run for 7 consecutive days are not blocked.
