AS209622: the UPRESS-DRB network

AS209622 is an internet Autonomous System operated by UPRESS-DRB (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 AS209622?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS209622 was assigned to UPRESS-DRB by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS209622 currently announces 7 IPv4 block(s), totaling about 4.1 thousand addresses (4,096 in all), registered in the United States. Services from UPRESS-DRB are reached through these addresses.

What it means to see AS209622 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS209622. That means the other end sits on the UPRESS-DRB network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
