Testar grátis 14 dias →AS1403 is an internet Autonomous System operated by EBOX (Canada). Here is what that means and why this number may show up when you investigate a connection on your network.
What is AS1403?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS1403 was assigned to EBOX by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS1403 currently announces 65 IPv4 block(s), totaling about 336.9 thousand addresses (336,896 in all), registered in Canada. Services from EBOX are reached through these addresses.
What it means to see AS1403 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS1403. That means the other end sits on the EBOX 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.
