What is an ASN and Why Does It Matter?
An ASN (Autonomous System Number) is a unique identifier assigned to networks on the internet. Every time you browse a website, stream content, or send an email — your internet traffic passes through these ASNs.
They’re used by ISPs, data centers, and cybersecurity experts to trace network routes and identify malicious IP ranges or suspicious traffic sources. If you're into networking, ethical hacking, or SEO tech, knowing how to look up ASN details is a super handy skill.
🔧 How It Works
This tool uses the ipinfo.io API, which offers real-time IP intelligence data, including ASN, city, country, and org info. It’s quick, reliable, and works globally.
