Buying Agent: Global Supplier Review

How exactly do you buy a proxy IP? You'll understand after reading this

Recently, many friends asked me how to choose a proxy IP, dozens of providers on the market to see people dazzled. As an old driver who has used the services of seven or eight, today to tell the truth. Don't believe in those flowery advertisements, the key to look at these hard indicators.

First, the choice of proxy IP have to look at these destiny

Responsiveness is the lifeblood，特别是做数据采集的朋友。上个月测试某家服务商，高峰期飙到800ms+，数据抓取直接变龟速。后来换到ipipgo的独享线路，稳定在80-120ms，这才是干活该有的速度。

moreoverIP pool qualitySome vendors claim to have millions of IPs, and the measured repetition rate is as high as 30%. Here we teach you a testing method:

import requests
proxy_list = ['ip1:port','ip2:port'...]  Fill in the proxies to detect
seen_ips = set()
for proxy in proxy_list.
    res = requests.get('http://ip-api.com/json', proxies={'http': proxy})
    seen_ips.add(res.json()['query'])
Repeat rate = 1 - len(seen_ips)/len(proxy_list)

ipipgo's measured repetition rate is less than 5%, this point is really more conscientious than peers. Their boss said that the 20%IP pool is updated every day, so it seems that it is not bragging.

II. Don't step on these pits

Last year was a provider pitched a tragedy, said the static residential IP, the result is all the room IP. later found aDetection Tips::

Now with ipipgo's location services, directly on the map to select a specific city street, to the U.S. IP will choose New York Manhattan, to the Japanese IP will choose Tokyo Shinjuku, the accuracy can be up to 500 meters range.

Third, the actual comparison of these service providers

Take the last three months of real-world data:

Special mention to ipipgo'sFailover mechanismThe system automatically cuts the backup node when the IP fails, which is too important for scripts that need to run 24 hours a day. The last time I dropped out at two o'clock in the middle of the night, the system automatically cut the line three times, and in the morning to see the data is not broken at all.

Fourth, white common questions and answers

Q: How much is the right amount to buy for the package?
Depending on the usage scenario, the 5GB/month starter package is sufficient for personal testing. Enterprise users directly on the customized version, ipipgo recently came out with a pay-as-you-go model, how much to use how much is quite cost-effective.

Q: How can I tell if a proxy is blocked?
Use this test command:

curl --proxy http://用户名:密码@IP:port https://httpbin.org/ip -m 10

If you don't respond for more than 10 seconds, you should change your IP address. ipipgo can look at the IP health status directly from the background.

Q: What if I need IPs from multiple locations at the same time?
Directly choose the global package, ipipgo supports 130+ countries line mixing. The last time I helped a customer do cross-border e-commerce, at the same time hanging the United States, Germany, Japan IP to monitor the price of a single account.

V. Say something heartfelt

The biggest lesson learned from using a proxy IP for the past three years is thatDon't be cheap.The 9.9 monthly subscription is absolutely impossible to use, either speed limit or IP quality is poor. ipipgo's price is considered to be mid-range, but the victory in the stability of the heart. Their technical customer service is really 7 × 24 online, once I raised a work order at three o'clock in the morning, ten minutes to solve the IP jitter problem.

As a final reminder to newbies, before you buy, be sure toApply for a test! Regular manufacturers will give a trial amount, ipipgo new users can receive 1G traffic for free, enough to measure the real effect. Remember, what works for others doesn't necessarily work for you, it's most reliable to try it yourself.
