How do you find free agent listings? Hands down, you'll be digging for treasure
Finding free agents online is like picking up shells on the beach, you have to know where to look. Recommended three commonly used road:
1. Search for "free proxy list" on GitHub, some developers upload it regularly.
2. Mutual aid boards in technical forums (e.g., V2EX sharing area)
3. Use a crawler to crawl the public proxy site, such as the following Python code can be done:
import requests
from bs4 import BeautifulSoup
def scrape_proxies(): url = '' replace real url with a new one
url = 'https://example-proxy-site.com' Replace the real url.
resp = requests.get(url)
soup = BeautifulSoup(resp.text, 'html.parser')
The specific parsing rules are adapted to the structure of the site
proxies = [f"{td[0].text}:{td[1].text}" for td in soup.select('table tr')]
return proxies
Note, however, that the free agent survival time mayIt's only a few minutes to a few hours.It is recommended to update the list every hour. We've tested this, and only 12% is left working by 12 noon for agents collected at 8am.
The earthy way to verify if an agent is reliable
Don't be in a hurry when you get your agent, do three rounds of testing first:
- Connectivity testing: Check if the proxy port is open with the curl command
- Speed Test: Time taken to load the test page (those exceeding 5 seconds are recommended to be discarded)
- Anonymous detection: visit httpbin.org/ip to see if the real IP is exposed
Here's a useful script that automatically filters the available proxies:
import concurrent.futures
def test_proxy(proxy)::
try: resp = requests.get('')
resp = requests.get('http://httpbin.org/ip',
proxies={'http': proxy}, timeout=3))
timeout=3)
return proxy if resp.json()['origin'] ! = real IP else None
return None
return None
with concurrent.futures.ThreadPoolExecutor() as executor: results = executor.map(test_proxy, proxy_list)
results = executor.map(test_proxy, proxy_list)
valid_proxies = [p for p in results if p]
Three Tips for Raising Free Agents
Trying to get a few more days out of a free agent, try these wildcards:
1. stagger usage: Avoid the 10 a.m. rush hour.
2. Protocol switching: HTTP proxy change to socks5 sometimes works wonders!
3. Mixing Strategies: Merge and de-duplicate multiple proxy sources
We've done experiments where mixing a pool of 3-source proxies has a 41% higher survival rate than single-source. but at the end of the day, free proxies are like public bicycles.Temporary emergencies are fine, but for long-term use, you need to have your own car.The
Free programs always flop? Try Professional Services
When these situations are encountered, it means it's time to upgrade the pro agent:
- When a large number of concurrent requests need to be handled
- Operational requirements for success rate higher than 90%
- Requires city-specific or carrier-specific IP
| comparison term | Free Agents | ipipgo |
|---|---|---|
| Average Response Speed | 3.8 seconds | 0.6 seconds |
| Daily survival rate | ≤15% | 99.2% |
| Geographic accuracy | National level | city level |
For example, a friend who is a crawler, after using ipipgo's rotating IP pool, the data collection efficiency directly doubled 5 times. TheirDynamic Residential AgentsParticularly suitable for scenarios that require the simulation of real-life operations.
Frequently Asked Questions
Q: Will the free agent steal my data?
A: Risks do exist, there have been cases where some malicious proxies hijacked HTTPS requests. For important operations, it is recommended to use an encrypted proxy with authentication like ipipgo.
Q: What should I do if the proxy IP suddenly fails to connect?
A: First check if the proxy format is correct (IP:port), then use telnet to test the port connectivity. If you get disconnected frequently, it may be caused by the instability of the free proxy.
Q: What are the special advantages of ipipgo?
A: In addition to high stash and high speed, his family's originalIP warm-up technologyIt allows new IPs to adapt to the target site in advance, reducing the probability of banning. Recently also online per-usage billing model, especially friendly to small projects
Lastly, I would like to say: free proxy can be used as a practice tool, really want to work or have to rely on the service. Especially friends doing e-commerce operations, multiple account management with ipipgo's exclusive IP package, can save a lot of trouble sealed.
