What is AS49203?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS49203 was assigned to IRM-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS49203 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS49203. That means the other end sits on the IRM-AS network (Romania). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
