Have you heard of ASN? If not, with the growing conversation around sovereignty, this topic is about to become very important.

Today, the vast majority of companies don’t have one. They access the internet through one or two providers who handle everything on their behalf. It’s simple, convenient, but it also means total dependency.

An Autonomous System Number is a unique identifier that allows you to independently manage your own routing on the internet.

In plain terms: it’s the number that gives you the right to speak BGP, the protocol that governs how data flows across the internet.

If you already have an ASN, peering becomes interesting as soon as two signals appear: latency issues on certain traffic flows, or transit costs that are starting to add up.

That’s where joining an IXP changes the equation, giving you direct access to the players you exchange the most traffic with, without going through an intermediary.

If that’s not the case yet, an ASN is the first step, and it’s an accessible one. In Europe, an ASN is obtained through the RIPE NCC.

And once you have it, local peering and France-IX’s Multipass let you reach as many interconnection points as possible from a single connection.

So if you’ve decided it’s time to stop relying on a single internet access provider and take control of your own traffic flows, come talk to us!
