[RFC PATCH v3] Configure the Node a routable ula v6

[mail at adrianschmutzler.de]

Hallo zusammen,

gleich zwei Fragen/Anmerkungen hierzu:

1. Im Keyserver ist der slash im ula-prefix escaped:

"ula_prefix":"fd43:5602:29bd:4::\/64"
http://keyserver.freifunk-franken.de/v2/?lat=49&long=10

Bitte das wegmachen!

2. Christian nimmt unten die Mac für die rechten 64 bit der ULA. Muss das
nicht die Interface ID sein?

https://tools.ietf.org/html/rfc4193

unter Punkt 3.1 ...?

Beste Grüße

Adrian
