For a side note, I can mention DN42 (1) uses fc00::/7 space (0), with
different participants using a mix of whatever you can find (FRR,
Bird1/2, XORP, Quagga, EdgeRouter, Mikrotik, OpenBGPd, IOS, IOS-XR,
JUNOS, etc.)

[0]: fc00:0000:0000:0000:0000:0000:0000:0000 -
fdff:ffff:ffff:ffff:ffff:ffff:ffff:ffff
[1]: https://dn42.us
