AS49223 is an internet Autonomous System operated by EVEREST-AS (Ukraine). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS49223?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS49223 was assigned to EVEREST-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS49223 currently announces 78 IPv4 block(s), totaling about 79.1 thousand addresses (79,104 in all), registered in Ukraine. Services from EVEREST-AS are reached through these addresses.

What it means to see AS49223 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS49223. That means the other end sits on the EVEREST-AS network (Ukraine). 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.
