AS207487: the ROUTING-CAFE network

AS207487 is an internet Autonomous System operated by ROUTING-CAFE (the Netherlands). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS207487?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS207487 was assigned to ROUTING-CAFE by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

AS207487 currently announces 1 IPv4 block(s), totaling 256 addresses (256 in all), registered in the Netherlands. Services from ROUTING-CAFE are reached through these addresses.

What it means to see AS207487 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS207487. That means the other end sits on the ROUTING-CAFE network (the Netherlands). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
