AS224: the UNINETT UNINETT, The Norwegian University & Research Network network

AS224 is an internet Autonomous System operated by UNINETT UNINETT, The Norwegian University & Research Network (Norway). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS224?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS224 was assigned to UNINETT UNINETT, The Norwegian University & Research Network by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS224 currently announces 16 IPv4 block(s), totaling about 1.1 million addresses (1,050,944 in all), registered in Norway. Services from UNINETT UNINETT, The Norwegian University & Research Network are reached through these addresses.

What it means to see AS224 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS224. That means the other end sits on the UNINETT UNINETT, The Norwegian University & Research Network network (Norway). 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.
