What is an ASN?
An Autonomous System Number identifies a network (an ISP, a cloud provider, a large enterprise) that has its own routing policy on the public internet. ASNs are how BGP — the protocol that holds the internet together — knows which network owns which range of IP addresses. AS196797 is the ASN assigned to CityTeleNet Joint Stock Company TransTeleCom.
If you want to know which ASN your connection is on, visit the home page — your ASN is shown alongside your public IP.
