AS203478 / tbspace Networks
AS203478 / tbspace Networks is an IPv6-only provider, which is operated by me for experimental use.
A Linux router with BIRD as routing daemon takes care of the announcements.
The Linux VM has an entry in the kernel routing table for every other network on the Internet and is therefore in the default free zone. At the beginning of 2017 there were about 38000 networks in the routing table.
Hurricane Electric and NetAssist are used as transit providers, which are connected via 6in4/protocol 41 tunnels.
Also connected to the network is a RIPE Atlas-Probe, which makes measurements from the point of view of my network.
Hurricane Electrics excellent BGP Toolkit has more information on the network.
