AS58580: the FASTRACK Fastrack Technology network

AS58580 is an internet Autonomous System operated by FASTRACK Fastrack Technology (Australia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS58580?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS58580 was assigned to FASTRACK Fastrack Technology by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS58580 currently announces 10 IPv4 block(s), totaling about 7.7 thousand addresses (7,680 in all), registered in Australia. Services from FASTRACK Fastrack Technology are reached through these addresses.

What it means to see AS58580 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS58580. That means the other end sits on the FASTRACK Fastrack Technology network (Australia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
