AS202520 is an internet Autonomous System operated by SKYPASS-AS (Poland). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS202520?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS202520 was assigned to SKYPASS-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS202520 currently announces 8 IPv4 block(s), totaling about 3.1 thousand addresses (3,072 in all), registered in Poland. Services from SKYPASS-AS are reached through these addresses.

What it means to see AS202520 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS202520. That means the other end sits on the SKYPASS-AS network (Poland). 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.
