Dynamic Crawler Proxy: Dynamic Crawler Proxy IP Pool | Data Collection Automatic Switching Anti-blocking

What exactly is the purpose of the Dynamic Crawler Proxy IP Pool?

What do you fear the most when doing data collection? I've been working hard to write a crawler script, but in the end, just after two days of running it, I've beenbe presented with a bucket of goodies. This time it is necessary to rely on dynamic IP pools to play guerrilla warfare - like playing hide and seek constantly change location, so that the site can not distinguish whether you are a real person or a program. ipipgo's residential IP pool from the real home network, more difficult to be identified than the IP room, more than 90 million addresses in turn, crawling efficiency can be turned up to the top of the rise. The efficiency of capturing can go up and up.

Build an Anti-Blocking Proxy Pool in Three Steps

Let's straighten out this circular process first:Get IP→Verify Availability→Automatic Switching→Retry AbnormallyTake ipipgo's Dynamic Residential IP as an example. Take ipipgo's Dynamic Residential IP for example, their API can change the exit IP on a minute-by-minute basis with this easy solution below:

Here's the kicker.switching strategyDon't be silly and change IP for every request, this is easy to trigger the wind control instead. It is recommended to switch intelligently according to the frequency of visits, such as 20 consecutive visits to the same site and then change to a new IP, which is both resource-saving and natural.

ipipgo practical guide to avoiding pitfalls

I've used seven or eight proxy service providers and found that dynamic proxies have to look at these three points to be stable:IP purity, response time, protocol compatibilityThe fact that ipipgo supports socks5 and http(s) protocols is a good thing, especially when collecting websites with strange ports, you don't have to convert protocols.

There's a detail that's easy to overlook--time zone matching. For example, the collection of domestic e-commerce sites, with local residential IP access is less likely to be recognized. Before helping customers to catch Japanese Lotte data, specially selected ipipgo Tokyo node, the success rate directly from 60% soared to 92%.

Frequently Asked Questions

Q: What should I choose between dynamic and static IPs?
Look at the business scenario! Dynamic is good for high-frequency collection (e.g., price monitoring), and static is good for those that need to maintain a session (e.g., autofill). But ipipgo both types can be seamlessly switched.

Q: How can I tell if my IP is blocked?
Don't wait until you're blocked! Recommended to do it every half hourHealth Screening, when 3 consecutive requests timeout or return 403, kick this IP out of the available queue.

Q: Why are residential IPs more expensive than server room IPs?
It's like the difference between staying in a hotel and staying in your own home - server room IPs are generated in bulk and easily recognized by websites. ipipgo's residential IPs come from real home broadband, and each IP has a much "cleaner" usage history.

The ultimate in anti-blocking

At the end of the day, anti-blocking isn't a purely technical issue, it'sThe Art of Behavioral Simulation. In addition to changing IPs, pay attention to these details:

• Randomize the request interval (don't use a fixed sleep time)
• Rotate User-Agents (don't just use Chrome)
• Control concurrency (a sudden 100x spike is obvious to anyone)

Lastly, here's a good one: set it up with the ipipgo API.IP territorial whitelisting, so that all requests come from a specific city, with the local language version of the browser header, this camouflage effect is directly pulled full circle.
