Eight cities.
One engineer.
IPv6 only.

AS205794 — the RTTW Education & Research Network — is a personal autonomous system run by Jinze Yang for learning how the Internet actually routes. Three RPKI-signed IPv6 prefixes, announced from eight points of presence across three continents, open to peering wherever we share a fabric.

Everything a session needs, in one object.

  • If we share a fabric, we peer. Send a request over any of the exchanges above — sessions are usually up within a day or two.
  • Filter us on AS205794:AS-SET and set an IPv6 max-prefix of 100.
  • Private sessions and research tunnels welcome. This is an experimental network — if you want to try something, ask.
