[PATCH v5] Configure the Node a routable IPv6 ULA

[mail at adrianschmutzler.de]

Hallo,

die Frage habe ich auch schon gestellt.

Nachdem ich etwas drüber nachgedacht habe, sehe ich den Charme der kürzeren
Variante.

In meinen Augen am besten wäre aber, wie bei fdff beide Adressen anzubieten,
einmal die direkt aus der Mac und einmal die korrekte mit EUI-64.

Weiß aber nicht, ob das möglich ist.

Grüße

Adrian
