What is AS58256?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS58256 was assigned to REFATEC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS58256 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS58256. That means the other end sits on the REFATEC network (Iran). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
