Find yourself in the Internet

See where your network's Autonomous System (AS) sits in the k-core decomposition of the whole Internet AS topology.

What is this?

The Internet is a network of networks: tens of thousands of Autonomous Systems (ASes), each run by a provider, university, company or organization. Your IP address belongs to one of them.

This page finds that AS and marks it on a LaNet-vi picture of the whole AS topology, built from the latest CAIDA AS-relationship snapshot.

How to read the numbers

  • k-core: every AS in the k-core has at least k neighbors that are also in it. Deeper cores are drawn closer to the center.
  • Deeper than X%: the share of all ASes in shallower shells. Most ASes are in the outermost shells, so a modest k-core is already deeper than most of the Internet.
  • Direct neighbors: ASes with a customer, provider or peer relationship with yours in the snapshot.

Data source

AS-relationship data from CAIDA (Center for Applied Internet Data Analysis), a monthly snapshot of the customer-provider and peer relationships inferred from BGP.

Your AS comes from a whois lookup of your public IP address (Team Cymru, with ipinfo as fallback). The address is not stored.
