AS204345
I run my own network, AS204345, for educational purposes (and for fun!). It is IPv6-only internally, with translation mechanisms at the edge on other providers' IPv4 networks.
I am open to peering at KleyReX or via a tunnel - please contact me for more details.
A looking glass is available, which allows running traceroutes and interacting with BIRD on the routers.
