Even as I (have to) totally agree with Nico, too; the sad reality as I 
had to observe it: For some reason some/many people are totally unaware 
of the possibility of IPv4 transport via IPv6. Be it using MP-BGP or 
nowadays Babel, too. This should get more "advertisement"/awareness.

But on the other hand: I have heard stories of unlucky sysadmins 
maintaining totally broken/cluttered networks with no clear vision how 
to enable IPv6, and they never got a proper address planning scheme and 
they have to live with no more space in RFC1918. These people would 
benefit of making 240/4 a configurable option.


I wish everyone a good fortnight, too, and stay safe!
