AS32590: the VALVE-CORPORATION network

AS32590 is an internet Autonomous System operated by VALVE-CORPORATION (the United States). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS32590?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS32590 was assigned to VALVE-CORPORATION by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS32590 currently announces 18 IPv4 block(s), totaling about 13.6 thousand addresses (13,568 in all), registered in the United States. Services from VALVE-CORPORATION are reached through these addresses.

What it means to see AS32590 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS32590. That means the other end sits on the VALVE-CORPORATION network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
