Testar grátis 14 dias →AS577 is an internet Autonomous System operated by BACOM (Canada). Here is what that means and why this number may show up when you investigate a connection on your network.
What is AS577?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS577 was assigned to BACOM by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS577 currently announces 564 IPv4 block(s), totaling about 6.8 million addresses (6,829,568 in all), registered in Canada. Services from BACOM are reached through these addresses.
What it means to see AS577 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS577. That means the other end sits on the BACOM 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.
