What is AS61209?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS61209 was assigned to USB-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS61209 currently announces 3 IPv4 block(s), totaling about 1 thousand addresses (1,024 in all), registered in Iran. Services from USB-AS are reached through these addresses.
What it means to see AS61209 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS61209. That means the other end sits on the USB-AS network (Iran). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
