What is AS39819?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS39819 was assigned to PROHOST by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS39819 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS39819. That means the other end sits on the PROHOST network (KG). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
