Testar grátis 14 dias →AS5617 is an internet Autonomous System operated by TPNET (Poland). Here is what that means and why this number may show up when you investigate a connection on your network.
What is AS5617?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS5617 was assigned to TPNET by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS5617 currently announces 68 IPv4 block(s), totaling about 5.5 million addresses (5,478,400 in all), registered in Poland. Services from TPNET are reached through these addresses.
What it means to see AS5617 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS5617. That means the other end sits on the TPNET network (Poland). 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.
