What is AS26189?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS26189 was assigned to SCI-ASN by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS26189 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS26189. That means the other end sits on the SCI-ASN network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
