What is AS210804?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS210804 was assigned to GKD by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS210804 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS210804. That means the other end sits on the GKD network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
