AS48620: the BEAMING network

AS48620 is an internet Autonomous System operated by BEAMING (the United Kingdom). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS48620?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS48620 was assigned to BEAMING by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS48620 currently announces 3 IPv4 block(s), totaling about 10.5 thousand addresses (10,496 in all), registered in the United Kingdom. Services from BEAMING are reached through these addresses.

What it means to see AS48620 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS48620. That means the other end sits on the BEAMING network (the United Kingdom). 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.
