What is AS855?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS855 was assigned to CANET-ASN-4 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS855 currently announces 274 IPv4 block(s), totaling about 782.1 thousand addresses (782,080 in all), registered in Canada. Services from CANET-ASN-4 are reached through these addresses.
What it means to see AS855 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS855. That means the other end sits on the CANET-ASN-4 network (Canada). 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.
