AS201382: the LUX-RS-BLG-ACB network

AS201382 is an internet Autonomous System operated by LUX-RS-BLG-ACB (Romania). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS201382?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS201382 was assigned to LUX-RS-BLG-ACB by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS201382 currently announces 4 IPv4 block(s), totaling about 1.8 thousand addresses (1,792 in all), registered in Romania. Services from LUX-RS-BLG-ACB are reached through these addresses.

What it means to see AS201382 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS201382. That means the other end sits on the LUX-RS-BLG-ACB network (Romania). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
