Never trust a proxy list blindly. Write a simple Python script using requests:
import requestsproxies = open('proxies.txt').read().splitlines() working_proxies = []
for proxy in proxies: try: response = requests.get('http://httpbin.org/ip', proxies='http': f'http://proxy', 'https': f'http://proxy', timeout=5) if response.status_code == 200: working_proxies.append(proxy) print(f"Working: proxy") except: pass Reflect4 Proxy List UPD Free
print(f"Found len(working_proxies) working proxies out of len(proxies)")
Because proxy lists change by the minute (proxies go offline, IPs get banned), you cannot rely on a single stored text file. Here is how the pros get the live, updated list for free.
proxy = random.choice(proxy_list) proxies_dict = "http": f"http://proxy", "https": f"https://proxy" Never trust a proxy list blindly
try: response = requests.get("https://httpbin.org/ip", proxies=proxies_dict, timeout=5) print(f"Using proxy: proxy - Response: response.json()") except: print("Proxy failed, rotating to next...")
