IPv4 Protocol Limitations: IPv4 Proxy Solutions

Why is IPv4 not enough?

Nowadays, there are more Internet devices than ants, and the total 4.3 billion IPv4 addresses have long been divided up. For example, your router is connected to a cell phone, computer, smart speakers, but may only be divided into a public IP. this time to do data collection or batch operation, the website found that the same IP frequent visits, directly pull you blacklist.

What's more troublesome is that some regional IP segments are specially marked, such as cross-border e-commerce with domestic IP access to overseas platforms, the other party to look at the IP belongs to raise the level of wind control. At this time it is necessary toProxy IP for a makeoverthat makes the server think it's accessing real users from different regions.

How do proxy IPs break the mold?

Here is a real case: an e-commerce company to monitor the price of competing products, with their own office network to check the 200 times on the blocked IP. changed to dynamic residential proxy, each request automatically switch to different areas of the home broadband IP, continuous monitoring for 3 days did not trigger the limit.

 Python example: extracting proxies with ipipgo's API
import requests

api_url = "https://api.ipipgo.com/getproxy"
params = {
    "key": "Your API key",
    "protocol": "socks5",
    "count": 10,
    "country": "us"
}
response = requests.get(api_url, params=params)
print(response.json()['proxies'])

This code gets 10 US residential proxies at once, accessed using the socks5 protocol. The key is to pickReal Residential IPIt's useless to use more than one of those server room IPs.

What are the doors to look for when choosing an agent?

In particular.TK LineThis is a good thing, specifically for specific platforms to optimize the delay. Last time, there is a customer who does live broadcasting, using ordinary proxy always lagging, after changing into TK dedicated line latency from 800ms down to 150ms.

Frequently Asked Questions QA

Q: How often does the Dynamic Proxy IP change?
A: ipipgo's standard package switches automatically in 15 minutes, and the enterprise package supports switching by request. But don't switch too often, some sites will detect the IP survival time!

Q: How can I prevent my proxy IP from being blocked?
A: three tips: 1. with the browser fingerprinting camouflage 2. control the frequency of access 3. with residential IP, not server room IP. we have a customer with this method, a single IP survived for 37 days.

Q: How to use the IP extracted by API?
A: It is recommended to use the polling mechanism, randomly select an IP for each request, pay attention to the setting of the timeout to retry, and automatically switch to the next failed IP.

Guide to avoiding the pit

Some agents will putblacklisted IPWhen new IPs are sold, here's how to teach you how to detect them:

curl --socks5 proxy IP:port https://httpbin.io/ip

10 consecutive tests, if the return IP less than 5, it means that the quality of IP pool is not good. ipipgo's Enterprise Package CommitmentIP availability ≥95%, measured basically gets to about 98%.

Finally, a piece of cold knowledge: now some sites will detect IP'sASN numberThe residential proxies of ipipgo are real carrier ASNs, unlike those fake residential proxies that are actually server room ASNs, which will be revealed as soon as they are checked.
