What is AS5377?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS5377 was assigned to MARLINK-EMEA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS5377 currently announces 18 IPv4 block(s), totaling about 96.3 thousand addresses (96,256 in all), registered in Norway. Services from MARLINK-EMEA are reached through these addresses.
What it means to see AS5377 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS5377. That means the other end sits on the MARLINK-EMEA 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.
