What is ASN: Proxy IP Services in ASN Networks Explained

ASN is a proxy IP ID? Let's look at this example first

Lao Zhang recently helped the company to do e-commerce crawler, found that the target site always blocked IP. changed 3 proxy service providers or be recognized, until the use of ipipgo'sASN Customized ServicesOnly then was it resolved. The key hidden in this story is ASN (Autonomous System Number). Simply put, ASN is like the zip code of the network world, and each operator has its own unique number, such as China Telecom AS4134, Mobile AS9808.

ASN in Proxy IP Services Practical Manual

You can't just look at the geographic location when choosing a proxy IP, the ASN directly affects the effectiveness of the use:

Take ipipgo's service as an example of theirASN FilterYou can directly check the type of network you need. For example, if you do overseas e-commerce, choose Amazon AWS's ASN (AS16509) proxy, and the access success rate can be increased by more than 60%.

3 Steps to Check ASN Information

1. Open the online tool provided by ipipgo (no link here)
2. Enter the IP address to be queried
3. View the returned AS number and operator information

 Python Sample Code
import requests

def get_asn(ip): api_url = "
    api_url = "https://api.ipipgo.com/asn-check"
    params = {'ip': ip, 'key': 'your_api_key'}
    response = requests.get(api_url, params=params)
    return response.json()

print(get_asn("203.34.56.78"))

Three Myths of ASN Applications

Myth #1:The less you see of ASN, the better.
(Re! Certain niche ASNs have been highlighted)
Myth #2:The ASN and IP affiliation must be the same
(Wrong! AWS's ASN has nodes all over the world)
Myth #3:One ASN to the end.
(ASNs should be rotated according to the business cycle)

QA Time: High Frequency Questions and Answers

Q: How can I tell if the ASN of the proxy IP is pure?
A: Use ipipgo's ASN health check tool, which will show the history of bans for that ASN

Q: Why is it sometimes still recognized after changing IP?
A：Possibly the IP under the same ASN is associated, it is recommended to turn on the ipipgo backgroundRandom switching across ASNsfunctionality

Q: What ASN parameters do enterprise applications need to focus on?
A: Focus on these three indicators:
1. Length of ASN survival (3+ years preferred)
2. Number of associated IPs (500+ recommended)
3. Network type (residential/data center/hybrid)

ipipgo's ASN black technology

They have a family.ASN cloning technologyIt's interesting to be able to simulate the ASN characteristics of a proxy IP as a specified carrier. For example, disguise the server room line as a home broadband ASN, and test the survival time in social media scenarios, which is 4 times longer than ordinary proxies.

recently updatedASN Hot ListThe function is also practical, displaying the utilization density of each ASN in real time. When the utilization rate of an ASN exceeds the alert line, the system will automatically assign cold ASNs, and this design is especially friendly to those who do bulk registration.
