Free Proxy IP List|Daily updated HTTP/SOCKS5 Proxies

Why do you need to keep an eye on how often proxy IPs are updated?

Many people encounter this situation when using proxy IPs: IPs that work in the morning suddenly fail in the afternoon. This is becauseFree proxy IPs generally have shorter survival timesThe IPIPGO technical team has found that the average survival time of free IPs obtained from public channels is less than 3 hours, and there are problems such as slow response time and poor anonymity.

For scenarios that require a stable network environment (such as batch data collection), it is recommended to choose a professional service provider. Taking IPIPGO as an example, its dynamic residential IP pool is automatically refreshed every 15 minutes, which, together with the intelligent routing algorithm, ensures that users always get available nodes.

What exactly is the difference between HTTP and SOCKS5 proxies?

The differences can be clearly understood by comparing the tables:

IPIPGO, as a fully protocol-supported service provider, allows users to freely switch protocol types according to their needs. Its uniqueProtocol Adaptive TechnologyIt automatically matches the connection method that best suits the current network environment.

Three-step technique to filter available proxy IPs

Even if you use a free proxy, mastering these methods can improve your success rate:

1. Response Time Testing: Use the ping command to detect latency, and directly eliminate those exceeding 500ms
2. Verification of anonymity: Visit a testing site such as whoer.net to make sure the IP belongs to a different address than the real one.
3. stability testing: Access the target site continuously for 15 minutes and observe if there is any disconnection.

But manual screening is time-consuming and laborious, which is where IPIPGO's technology comes in. ItsIntelligent Screening SystemTwelve testing indicators have been preset to automatically filter unavailable nodes, and users can directly obtain quality IPs that have been verified and passed.

Practical tutorial: configure the correct posture of the proxy IP

An example of a Python crawler demonstrating how to quickly access an agent:

import requests

proxies = {
    'http': 'http://username:password@gateway.ipipgo.com:端口',
    'https': 'http://username:password@gateway.ipipgo.com:端口'
}

response = requests.get('destination URL', proxies=proxies)

Frequently Asked Questions QA

Q: Why do free proxy IPs often fail?
A: It is mainly due to the ownership change of IP resources and server load limitation. Professional service providers such as IPIPGO can effectively solve this problem through the 90 million + residential IP pool rotation mechanism

Q: What should I do if I can't connect after setting up SOCKS5 proxy?
A: Check the local firewall settings first to make sure the port is not blocked. When using IPIPGO service, it is recommended to enable itsIntelligent Routing ModeThe system automatically selects the optimal connection path

Q: How to determine whether the proxy IP exposes the real address?
A: Visit the IP Inspection website to view header information. ipIPGO all nodes are enabled by defaultAdvanced anonymous modeThe X-Forwarded-For field is a sensitive field that is completely hidden from the public.

It should be noted that, although this article introduces the use of free proxies, but for commercial-level application scenarios, it is recommended to choose IPIPGO such professional service providers.
