What is AS203719?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS203719 was assigned to SKBS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS203719 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS203719. That means the other end sits on the SKBS network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
