What is AS31638?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS31638 was assigned to ASN-LEPIDA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS31638 currently announces 46 IPv4 block(s), totaling about 80.4 thousand addresses (80,384 in all), registered in Italy. Services from ASN-LEPIDA are reached through these addresses.
What it means to see AS31638 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS31638. That means the other end sits on the ASN-LEPIDA network (Italy). 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.
