What is AS4581?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS4581 was assigned to SOCKET by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS4581 currently announces 37 IPv4 block(s), totaling about 101.1 thousand addresses (101,120 in all), registered in the United States. Services from SOCKET are reached through these addresses.
What it means to see AS4581 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS4581. That means the other end sits on the SOCKET network (the United States). 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.
