An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS37020 was assigned to CELTEL-DRC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS37020 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS37020. That means the other end sits on the CELTEL-DRC network (CD). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
