What is AS16573?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS16573 was assigned to SMCC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS16573 currently announces 5 IPv4 block(s), totaling 524 addresses (524 in all), registered in the United States. Services from SMCC are reached through these addresses.
What it means to see AS16573 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS16573. That means the other end sits on the SMCC network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
