Dynamic anonymous proxy: web crawler data collection dedicated dynamic anonymous proxy IP service recommendation

You can't do data collection these days without a little "face painting".

Recently and a few friends do crawler jerk, found that they are spitting the same problem: now the site anti-climbing mechanism more and more chicken thief, not moving to block IP. old Zhang said he wrote a crawler script last week, just run half an hour on the target site blacklisted, angry almost smashed the keyboard. At this time, someone on the table said: "Why don't you use dynamic anonymous proxy? It's just like the Sichuan opera, where you change your IP address every few minutes, so the website can't catch you at all". This sentence instantly woke up everyone present - the secret of fighting against blocking is here!

What's so hacky about dynamic proxies?

This simply means that every time a network request is initiatedAutomatically change to a different IP addressIt's like the art of disguise in a martial arts novel. Ordinary proxy with a fixed IP is like going out with the same mask, dynamic proxy is every few minutes to change a new face. Take ipipgo home services, they hold in their hands more than 90 million residential IP, the equivalent of tens of millions of "human skin masks" prepared for you, how you want to change how to change.

Here to pay attention to a misunderstanding: not just a proxy can pretend to be a real person. A lot of websites will now identify the crawler through the IP type, with the IP room in a minute to reveal. ipipgo's residential IP is a real home network, with the dynamic replacement mechanism, the site can not distinguish between a real person to visit or machine collection.

These scenarios are a recipe for disaster if you don't use dynamic proxies

1. Grab Tickets and VouchersThe last double eleven an e-commerce platform to engage in a limited number of seconds, with a fixed IP maniacal brush of the basic all gone. There is a buddy with a dynamic proxy every 0.5 seconds to change the IP, hard to grab 10 units of special phones!

2. Price comparison software data captureThe owner of a price comparison site said personally that they use dynamic IP pool polling to capture the prices of major e-commerce, if you use a fixed IP would have been blacked out!

3. Social Media Content MonitoringAs any company doing public opinion analysis knows, continuous tweeting/blogging with the same IP is bound to be restricted in less than half an hour.

You have to look at these three lifebloods to pick a dynamic agent

First LookIP purityThe first thing you need to do is to get your hands dirty. Before a cross-border e-commerce friends cheap buy a pheasant agent, the results of the IP has long been marked by the major platforms, the data did not pick up but was blocked account. ipipgo's residential IP are never been polluted "virgin number", with a silky smooth that is called.

Second LookProtocol SupportThe first thing you need to know is how to use the SOC5 protocol. Some proxies only support HTTP, encountered the need for SOC5 protocol scene directly to rest. In this regard, or the big manufacturers reliable, ipipgo all protocols ate the characteristics of the really save heart, what type of collection task can hold.

Third Lookresponsiveness。别信那些标榜低的广告词，实测才是王道。有个做直播数据监控的团队跟我吐槽，他们之前用的代理经常卡顿，导致数据缺失严重。换了ipipgo之后，50毫秒内的响应速度让采集效率直接翻倍。

The five soul-crushing questions that matter most to white people

Q: Do dynamic proxies count as gray operations?
A: The tool itself is legal, like a kitchen knife can cut vegetables can also hurt, the key to look at the use. Comply with the website robots agreement, control the frequency of access, don't screw up their servers on the line.

Q: Will frequent IP changes affect data accuracy?
A: Good question! ipipgo has a "IP geographic lock" function, for example, you want to collect data in Shanghai, although the IP has been changed, but it is guaranteed to be the local residential IP in Shanghai.

Q: Is it enough to open multiple crawler task IPs at the same time?
A: 90 million IP pool is a joke? Even if you open 1,000 concurrent tasks, each task every minute to change 1 IP, continuous running for 1 month can not use up one tenth.

Q: What should I do if I encounter a CAPTCHA?
A: Dynamic proxy is not a master key, but can significantly reduce the probability of triggering the CAPTCHA. Really encountered or have to rely on the coding platform, the two together with the best results.

Q: Are your dynamic proxies easily recognized?
A: ipipgo's residential IPs are obtained through regular carrier channels, and every time you change them, you will also automatically clean up cookies and browser fingerprints, so unless you are on a website with face recognition (just kidding), you won't be able to find out at all.

Tell the truth about offending your peers

There are some proxy service providers on the market that play word games and package data center IPs as residential IPs for sale. If you know what you're doing, you'll know that many of the so-called "residential proxies" actually come from the Amazon cloud, Aliyun, and these server rooms. ipipgo's strongest point is that it dares to provide IP traceability services, and each IP can be traced back to a specific home broadband address, which is called the real - residential proxy.

Finally, a piece of advice: do not buy those cheap dynamic proxy billed by the volume, when you really start large-scale data collection, the cost of minutes on the sky. Find a service provider like ipipgo that can provide a stable massive IP pool, but more cost-effective in the long run. After all, in the era of data is king, stable and reliable collection channel is your money printing machine.
