What is AS202348?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS202348 was assigned to YLEM by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS202348 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS202348. That means the other end sits on the YLEM network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
