AS197754 is a personal ASN with a focus on IPv6 mostly networking. The core of the network operates as IPv6 only, with legacy IP (IPv4) provided as an overlay service (IPv4aaS).

With this, AS197754 shows what networks will be like in the final stages of the IPv6 transition, where IPv4 is only provided as an interconnection service for legacy applications and devices. Through this network, I test software and standards on the operational aspects of running a network in such a scenario. AS197754 runs on the BIRD routing daemon (for now).

Network

AS197754 currently operates with two peering/border points of presence (PoPs) in Amsterdam (Iron Mountain AMS-1, Haarlem) and Enschede (InterDC Marssteden, Enschede).

If you are present at any IXP we share or with a server in one of the ColoClue racks at Iron Mountain AMS-1, feel free to contact me to setup a peering. Happy to help your network, both with peering and transit.

Peering Policy

IP Transit

  • Netwerkvereniging ColoClue (AS8283)1
  • Cedric Hoogendoorn/Fexxio Digital (AS210320)2
  • Nick Bouwhuis/Greybull (AS202585)3
  • Hurricane Electric (IPv6-only, AS6939)4

Partial transit through FrysLÂN (AS203291) and FreeIX Remote (AS50869) is also redundantly connected both through Frys-IX as well as ENS-IX. This helps ensure that AS197754 is always reachable from both IXPs, as well as many other smaller IXPs throughout Europe.

IXPs

  • Frys-IX (Nikhef, Amsterdam 🇳🇱) - connected by ColoClue from Iron Mountain AMS-1 to Nikhef
  • ENS-IX (InterDC Marssteden, Enschede 🇳🇱)
  • bgp.exchange Amsterdam - via VXLAN from IMDC

Thanks to

Except if you bring infinite financial backing, you will need some help. I want to thank these awesome people and organisations for providing that help for AS197754.

  • Netwerkvereniging ColoClue for inspiring me to start the AS, providing rack space, LIR services and a great community. Specifically, thank you Jelle for the guidance in the paperwork with RIPE NCC and some tips along the way.
  • Cedric (AS210320) and Nick (AS202585) for providing the initial VMs to start the network, providing IP transit and helping with physical connectivity.
  • Frys-IX (Arend & Pim) for creating a great community (#frys-ix on IRCnet) and providing a kick-ass IXP.
  • ENS-IX for providing me a great local peering point in Enschede.
  • apalrd for providing his Bird Ansible playbooks as a public resource and reference for me to create my own.
