AS20771: the CAUCASUS-CABLE-SYSTEM CCS Autonomous System network

AS20771 is an internet Autonomous System operated by CAUCASUS-CABLE-SYSTEM CCS Autonomous System (Georgia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS20771?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS20771 was assigned to CAUCASUS-CABLE-SYSTEM CCS Autonomous System by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS20771 currently announces 18 IPv4 block(s), totaling about 182 thousand addresses (182,016 in all), registered in Georgia. Services from CAUCASUS-CABLE-SYSTEM CCS Autonomous System are reached through these addresses.

What it means to see AS20771 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS20771. That means the other end sits on the CAUCASUS-CABLE-SYSTEM CCS Autonomous System network (Georgia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
