AS39591: the GLOBAL-E network

AS39591 is an internet Autonomous System operated by GLOBAL-E (the Netherlands). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS39591?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS39591 was assigned to GLOBAL-E by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS39591 currently announces 11 IPv4 block(s), totaling about 11.3 thousand addresses (11,264 in all), registered in the Netherlands. Services from GLOBAL-E are reached through these addresses.

What it means to see AS39591 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS39591. That means the other end sits on the GLOBAL-E network (the Netherlands). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
