What is AS200311?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS200311 was assigned to PREWIFI by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS200311 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS200311. That means the other end sits on the PREWIFI network (Italy). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
