Is geo-proxy positioning accuracy reliable or not? Teach you how to measure
Recently, a lot of friends asked me, when using proxy IP obviously selected the Shanghai node, how to show in Hangzhou? This is something I also stepped on last year. Today, we will take our team's actual test data to teach you how to verify the geographic location of the proxy IP is accurate or not.
Don't choose your testing tools, these are the real deal!
There are all sorts of location testing websites on the market, and these three are the most reliable:
1. ipipgo's own testing page (free)
Our own products surely know our own IP best, the data update frequency is synchronized on the same day, and we can also see the base station positioning deviation value.
2. A map API (specific name withheld)
3. Operator base station query tool
Cross-validation of these three tools basically keeps the error within 5 kilometers.
Four Steps to Testing Real World
Last week to help customers test ipipgo 200 Jiangsu IP, specifically so:
- Access detection tools with browser's no-trace mode
- Average of 3 consecutive requests per IP
- Record the straight-line distance between the actual coordinates and the target city
- Carrier attribution for labeled anomalous IPs
I found an interesting phenomenon after the measurement:Some IPs, although the city display is correct, the actual base station may cross to the next cityThis time it depends on how often the proxy service provider updates its IP database. This is where it depends on how often the proxy service provider is updated, like ipipgo updates their IP library twice a week, and this is much less of a problem.
Sources of Error Revealed
According to the data we compiled from 500 tests, the positioning bias comes mainly from:
| Type of error | probability of occurrence | cure |
|---|---|---|
| IP库更新 | 38% | Choose a service provider that updates its IP library in real time |
| base station positioning drift | 25% | With GPS analog positioning |
| Carrier Routing Strategies | 17% | Avoid using cross-province backbone nodes |
Here I want to praise ipipgo's dynamic compensation technology, they have a smart corrective algorithm that can suppress the base station drift error to within 3 kilometers.
Three Cold Facts About Choosing a Service Provider
1. Look at when the IP library is updated:Preferably updated on an hourly basisDon't believe those who just say "daily updates".
2. 测实际：定位接口响应超过200ms的直接pass
3. Check the history track: a good proxy IP should have a regular location movement records
QA time
Q: Why does the Shanghai IP I bought show up in Hangzhou?
A: 80% of the use of inter-provincial backbone IP, it is recommended that the ipipgo background screening "localized nodes", this type of IP directly go to the municipal operator exit!
Q: How much error in positioning accuracy is considered acceptable?
A: It depends on the specific scene. Advertising requirements within 10 kilometers, local life services preferably within 5 kilometers. ipipgo's enterprise version supports 3 kilometers of precision targeting!
Q: How is the frequency of testing organized?
A: Regular business weekly random testing 20% nodes, important business daily full detection. Remember to use automation scripts to save time, ipipgo provides free testing interface
The last nagging sentence, choose proxy IP service providers do not just look at the price. Like the last time a customer to buy a cheap service, the result of 30% IP positioning in the next province, the compensation of the liquidated damages are enough to buy ipipgo three years of service. The positioning accuracy of this matter, really a penny for a penny.
