What is AS9123?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9123 was assigned to TIMEWEB-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS9123 currently announces 264 IPv4 block(s), totaling about 234.8 thousand addresses (234,752 in all), registered in Russia. Services from TIMEWEB-AS are reached through these addresses.
What it means to see AS9123 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9123. That means the other end sits on the TIMEWEB-AS network (Russia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
How to see every connection and network your devices reach
Tracing one connection's ASN at a time is tedious. Sentinela, by PC Monitor, maps the devices on your network, shows what is exposed to the internet and helps flag suspicious connections and devices — running on your Windows. Meet Sentinela.
