代理IP的怎么测试：检测工具使用教程

手动土办法测

说白了吧，就是代理IP的网速快慢。最简单的办法就是countdown.. For example, if you visit a web page with a browser, the time from clicking the mouse to the end of the page loading. However, this kind of earth method is too much error, especially when encountering network fluctuations, may be measured today 10 seconds, tomorrow become 20 seconds.

Old drivers commonly used command line tools. For example, Windows systems open cmd to lose this:

ping proxy IP address -n 10

This trick looks at the average time of 10 round trips. But note that this only measures the proxy server's物理, you may have to account for the time difference in data processing when you actually use it.

Precise measurement with professional tools

To get accurate, you have to use specialized tools. We recommend three that have been tested and work well:

举个实际例子，用Python的requests库测：

import requests
import time

proxy = {'http': 'http://ipipgo账号:密码@代理IP:端口'}
start = time.time()
try:
    res = requests.get('http://example.com', proxies=proxy, timeout=10)
    delay = round((time.time()-start)1000)
    print(f'当前：{delay}毫秒')
except:
    print('IP已失效')

How to analyze the test results

There are three things to look for in the measured data:

1. amplitude of fluctuations: 10 consecutive measurements, the difference between the highest and lowest value exceeds 30% IP is recommended to be eliminated.
2. failure rate: If there are more than 3 time-outs out of 20 tests, you will be blackmailed directly.
3. time interval difference：早中晚各测一轮，避开高峰时段暴增的IP

For example, if you use ipipgo's static residential IP for testing, the measured data can be stabilized within 200ms. If it is a dynamic residential IP, it is recommended to pair it with theirIntelligent Routing功能，系统会自动选最低的节点。

QA Frequently Asked Questions

Q: What should I do if my test results are high and low?
A: eighty percent of the use of dynamic IP, change a static residential IP try. ipipgo static package from 35 yuan / month, do data collection with this most stable.

Q：需要测国外IP怎么办？
A：在本地测不准，最好用目标地区的服务器做测试。ipipgo的跨境专线能直接对接海外机房，测出来的更真实。

Q：When testing, it always prompts connection timeout?
A：先检查代理设置对不对，特别是账号密码里的特殊符号要用URL编码。比如@符号要写成%40，冒号是%3A。

Choosing the right service provider is important

测这事，七分看工具，三分看IP质量。像ipipgo这种有Carrier-grade resources的服务商，实测比市面普通IP低40%左右。特别是他们的TK专线，专门针对实时性要求高的业务做过优化。

Newbies are advised to practice first with Dynamic Residential Standard Edition, a $7.67/GB package. Enterprise level users go straight to the $9.47/GB Enterprise Edition withquality assurance (QA)的。别图便宜用免费IP，测出来的数据都是虚的，实际用起来坑更多。
