High-quality ip: high-quality IP screening configuration program, 99.9% availability rate

Hands on teaching you to sift through proxy IPs that really work

Friends engaged in data collection know that the biggest headache is the sudden failure of proxy IP. Last month our team tested the market seven service providers, the results of five IP survival time is not more than 15 minutes. Later changed the ipipgo screening program, and now continuous stable run for three weeks without turning over.

IP screening is not a matter of chance

Many people think that buying an agent isSee which one is cheaper and has more volumeI'm not sure if this is a good idea, but I think it's a good idea. Last week there was a friend doing e-commerce, figure cheap to buy a 0.5 yuan / IP package, the results of the account was blocked more than a dozen. Really reliable screening to see three hard indicators:

 Quickly check IP availability (Python example)
import requests

def check_ip(proxy)::
    try.
        resp = requests.get('http://httpbin.org/ip',
                          proxies={'http': proxy},
                          timeout=8)
        return resp.status_code == 200
    except: resp.status_code == 200
        return False

This script can quickly determine whether the IP can be used, focusing on response time and stability. Don't believe those who just say the response time, to real test!various periodsperformance. For example, we use ipipgo's residential proxy, which also guarantees a response within 800ms during peak hours.

There is a way to configure

I've seen too many cases of people using good IPs for nothing. Let's talk about a real case: a company bought 2000 IPs, and they all used the same User-Agent, and they were blocked on the same day. The right way to open should be:

Here's a special mention of ipipgo'sIntelligent RotationWe tested and found that with their TK line, the target website could not detect the crawler behavior at all.

Analysis of real-world cases

Last year to help a clothing brand to do competitive monitoring, they originally to manually change the IP 20 times a day, and then changed to use ipipgo's static residential package, directly configured with automatic switching rules:

 Example of automatic switching rules (pseudo-code)
if response time > 3 seconds.
    Change IP immediately
elif Fail 3 times in a row:
    Switch country node
else.
    Keep current IP

This program has been running for half a year, and the data collection integrity rate has shot up from 67% to 98%. special mention should be made of theircross-border rail line, handling visits to Southeast Asia is particularly steady.

Frequently Asked Questions Literacy

Q: How long should I observe the test IP quality?
A: Run for at least 24 hours, network conditions vary greatly from time to time. There is a tricky way - directly look at ipipgo backgroundSurvival Rate Monitoring Panel, much more accurate than manual testing.

Q: How to choose between dynamic IP and static IP?
A: regular collection with dynamic (cheap volume), need to log in the site with static. Like their static residential package, 35 dollars / IP can be used for a month, cheaper than the temporary buy number.

Q: What should I do if I encounter a sudden IP failure?
A: Don't be in a hurry to change your subscription! Check to see if you have a configuration problem first. ipipgo's tech support is very responsive, the last time we had a problem with a CAPTCHA, they solved it in 20 minutes.

Saving Program Recommendations

A final note on the configuration our team is using right now:
- Routine Collection: Dynamic Residential (Enterprise Edition) + Intelligent Rotation
- Difficult task: static homes + customized fingerprinting solutions
- Special needs: go directly to their technology for a 1v1 program

Special reminder: don't be fooled by low-cost packages! ipipgo's Dynamic Residential Enterprise Edition is a bit more expensive ($9.47/GB) but has a higher success rate than the standard edition of 18%. If it's a long-term project, it's recommended that you just go for the monthly package which is more cost-effective.
