What is AS21344?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS21344 was assigned to INTELIGO by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS21344 currently announces 4 IPv4 block(s), totaling about 1 thousand addresses (1,024 in all), registered in Poland. Services from INTELIGO are reached through these addresses.
What it means to see AS21344 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS21344. That means the other end sits on the INTELIGO 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.
