Testar grátis 14 dias →AS5529 is an internet Autonomous System operated by DIAG-AS (Switzerland). Here is what that means and why this number may show up when you investigate a connection on your network.
What is AS5529?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS5529 was assigned to DIAG-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS5529 currently announces 2 IPv4 block(s), totaling 512 addresses (512 in all), registered in Switzerland. Services from DIAG-AS are reached through these addresses.
What it means to see AS5529 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS5529. That means the other end sits on the DIAG-AS network (Switzerland). 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.
