Network Description

We are a group of researchers, and network/open-source enthusiasts at
the RWTH Aachen University in Germany. We operate AS207613 as a
non-commercial network for research and educational purposes. Our main
research topics are low-latency networks for Geographically Distributed
Real-time Simulations (GDRTS) 1.

The network currently consists of two PoPs in Falkenstein and Frankfurt
with plans to expand to a third PoP in Düsseldorf.

As a research network, we only test and operate IPv6. Various
measurement and monitoring tools are deployed in our network:


  • Aachen
  • Frankfurt: meerfarbig / Accelerated



AS207613 maintains an open peering policy, signed formal agreements are
not required. Peerings with other PRENs or non-profit
networks are welcome.

Physical interface

Peerings are possible at the following IXPs:

  • DE-CIX (Frankfurt, Germany)
  • KleyRex (Frankfurt, Germany
  • LocIX (Frankfurt, Germany)

Remote peering IXPs:

  • DE-CIX (Munich, Düsseldorf, Hamburg, Germany)
  • EVIX (Amsterdam, The Netherlands)
  • 4IXP (Zürich, Switzerland)

Remote peerings via WireGuard tunnels can be also used as a fallback.


Peerings with AS207613 are cost-neutral for both parties.

Routing & Filtering

  • Incoming routes are filtered against IRR (RIPE, APNIC, RADB, etc.)
  • Peers must not announce private address space (RFC1918, RFC4193)
  • Peers must not announce private ASNs
  • Peers must not configure static/default routes to our routers


AS207613 will announce prefixes for all members listed in the AS-SET
"AS-NULLL". AS207613 originates the following prefixes:


No explicit SLA is guaranteed. The /dev/null Research Network operates
on a best-effort basis.

Be sure to include your:

  • ASN & AS-SET
  • Prefix limit count
  • Preferred peering location
  • Peering LAN IP / Wireguard endpoint and key
