Core01-IX

Core01-IX

Core01-IX is a small Internet Exchange in Velbert, Germany, run by ShadowIP (AS218995). We started it in November 2026 so our own customers and a few friendly networks could peer directly instead of going through transit.

Joining is free. If you already have a VM with us, we put the IX VLAN on it. If you don't, we can bring you in over a tunnel, which is fine for small networks and hobby ASNs.

A few rules: one MAC per port, no proxy ARP, don't send us a default route, and keep IRR records up to date or your prefixes get filtered.

This list comes straight from our IX-F export: /api/v4/member-export/ixf

Join

Fill this in, or just email ixp@shadowip.org with your ASN. You need your own ASN, and a PeeringDB entry helps. We'll reply with your IPs and session details, usually the same day.

One tip: on your network in PeeringDB, tick Allow IXP Update. PeeringDB then imports our member list and creates your connection on the exchange by itself, so you never have to add it manually.
