What is AS50809?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS50809 was assigned to CMS-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS50809 currently announces 5 IPv4 block(s), totaling about 1.8 thousand addresses (1,792 in all), registered in Russia. Services from CMS-AS are reached through these addresses.
What it means to see AS50809 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS50809. That means the other end sits on the CMS-AS network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
