AS41589 is an internet Autonomous System operated by LGTECH-AS (Luxembourg). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS41589?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS41589 was assigned to LGTECH-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS41589 currently announces 4 IPv4 block(s), totaling about 12.8 thousand addresses (12,800 in all), registered in Luxembourg. Services from LGTECH-AS are reached through these addresses.

What it means to see AS41589 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS41589. That means the other end sits on the LGTECH-AS network (Luxembourg). 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.
