ASN Numbering Definition: ASN Agent Technology Explained

What the heck is an ASN number? Let's understand the logic of the ID card.

You should have seen the ID card number, right? ASN number is frankly the Internet service provider's "ID card number". Each operator has its own ASN, such as China Telecom AS4134, mobile AS9808. this number of global unified management, just like we can not just fake ID cards, ASN is also the whole network of unique authentication.

For example, with ipipgo check IP, the result of that "AS12345″ is the current IP belongs to the operator's number. What is the use of knowing this number? Look down and you'll understand!

ASN Agent's One-Trick Pony: Pinpointing Operators

Ordinary agents can only change regions, but ASN agents canPrecise targeting of specific carriersFor example, if you want to test the access speed of Unicom users in a certain province. For example, if you want to test the access speed of Unicom users in a certain province, a normal proxy may give you a mobile IP, but with an ASN proxy you can directly specify the ASN number of Unicom.

Hands-on with ASN Proxy

Take ipipgo's service as an example of a three-step approach to ASN proxy configuration:

 Sample code to get ASN proxy (Python version)
import requests

proxy_api = "https://api.ipipgo.com/asn-proxy?asn=AS4134" specifies the telecom ASN
resp = requests.get(proxy_api)
proxy_config = resp.json()

 Initiate the request using the proxy
proxies = {
    'http': f "http://{proxy_config['username']}:{proxy_config['password']}@{proxy_config['server']}",
    'https': f "https://{proxy_config['username']}:{proxy_config['password']}@{proxy_config['server']}"
}

response = requests.get('https://example.com', proxies=proxies)
print(response.text)

Notice in the code theasn=AS4134This parameter, this is to specify the use of China Telecom ASN proxy IP. ipipgo API can also specify the region and ASN, such as Shanghai Telecom's proxy, the parameter changed to asn=AS4134&city=shanghai on the line.

The real-world wonders of ASN proxies

1. Carrier compatibility testing: Some websites are optimized differently for different carriers' lines, using an ASN proxy can simulate the access of users from different carriers.

2. Precision advertising: Some promotions are only targeted to specific operators, using ASN agents is more accurate.

3. Competitive Analysis: Disguise as a competitor's ASN user to see if they have special policies for specific carrier users

QA session: what you might want to ask

Q: What is the difference between an ASN proxy and a regular proxy?
A: Just like the difference between ordinary courier and cold chain transportation, ASN agent has more precise positioning at the carrier level, which is suitable for scenarios that need to distinguish between carrier lines.

Q: Will I be blocked with ASN proxy?
A: Choose ipipgo this kind of high stash proxy service provider, their ASN proxy withAutomatic Fingerprint Disguiserespond in singingDynamic request for feature changesfunction, which is more secure than normal proxies.

Q: How do I check the ASN number of a website?
A: Using ipipgo's online tool, you can enter the domain name to see the ASN to which the web server belongs, and also check all the IP segments under that ASN.

Choose an ASN agent by looking at these doorways

1. Look.ASN coverage: ipipgo supports 30,000+ ASNs globally, with full coverage of mainstream domestic carriers.
2. Look.IP purity: Their proxy pool automatically cleans tagged IPs every 15 minutes.
3. Look.Protocol Support: In addition to regular HTTP/Socks5, Websocket proxy protocol is also supported.

As a final reminder, for business testing it is recommended to chooseLong-lasting ASN agentipipgo's dedicated line can keep the same ASN for 72 hours without changing IP, which is much more stable than public proxies. Encounter technical problems directly to their customer service, the response speed is much faster than some big manufacturers.
