Proxy server address how to find: free proxy server address get method

Hands-on with digging up free proxy addresses

Finding a proxy server is like finding a needle in a haystack. There are a lot of free resources on the internet, but there are not many reliable ones. Today we will nag a few wild methods, and finally give you a solid trick.

The Great Open Source Address Harvesting Method

Some tech forums are like food markets and you can often pick up the slack. Focus on theGitHub's gist pagerespond in singingPost a technical section of the bar, especially in the early morning hours when updates are most frequent. Be careful to look at the last three days of posts, more than a week are basically invalid.

 Quickly verify if a proxy is alive with Python
import requests

proxy = {"http": "123.45.67.89:8080"}
try: {"http": "123.45.67.89:8080"}
    resp = requests.get('http://httpbin.org/ip', proxies=proxy, timeout=5)
    print(f "Valid proxies: {resp.json()['origin']}")
except.
    print("This proxy is cool.")

Port Scanner Hunting

set upAdvanced Port ScannerThis kind of tool, set to scan 80/8080/3128 these common ports. Remember to slow down the scanning speed, otherwise you will be easily caught by the firewall. Scanning results with the word "proxy" in the server can focus on marking.

Browser Plugin Gold Rush

installProxy Helperplugin, which automatically grabs a list of public proxies. Be warned though, 8 out of 10 free proxies are the pits - either they slow down to a snail's pace, or they're useless after half an hour of use. I tried two dozen last week, and only two of them worked.

Free lunches don't taste good.

Frankly speaking, tossing these free agents is too much effort. Take my colleague Lao Wang for example, last week in order to engage in data collection, spend three days looking for agents, the results of the test found:

• 40%'s agent can't connect at all.
• The 30%'s are dropping out when I use them.
• The rest of it doesn't work as fast as his 2G network.

That's when it's time to consider the pros. The likes ofipipgoTheir home, directly to the ready-made quality agent pool. I have compared, people's response speed is more than seven or eight times faster than the free agent, the key is to be able to 24 hours stable online.

QA time

Q: Will the free agent leak data?
A: This is too common! Last year, a friend of mine who is an e-commerce company used a free proxy and his customers' information was intercepted. If you ask me, you need to look for a security solution.ipipgoThis has HTTPS encrypted regulars.

Q: Why can't the agent always connect?
A: Free proxy survival time is basically no more than 12 hours, and many of them are people's internal servers accidentally exposed, administrators will turn off when they find out. Professional service providers likeipipgoAll have a real-time monitoring system and automatically change to a new IP when they drop out.

Q: What software do I need to prepare?
A: You don't really need to install any special tools.ipipgoBackground directly generate the proxy address, copy the code can be used. Their documentation is written in a special understanding, white people follow to do ten minutes to run up.

At the end of the day, you can try free proxies for temporary use. Really need to work also rely on professional services, after all, time is money. Like I am now doing projects all useipipgoI'm sure you'll be able to get up in the middle of the night and change your IP address. Recently, I saw that they are engaged in activities, new users free to receive 3 days of experience time, want to test the water can go to the official website to take a look.
