I'm sure he meant ip addresses in use, not putting a /64 net on your
interface.

Not trying to start a huge discussion, but:
DHCP does the same thing with a smaller prefix, and also gives you the
correct dns-settings and/or bootp-options ++. Since you obviously think you
can get 2^64 devices on a single lan, dhcp can reject new devices an ip
address if there are none availible.

I know by now how much you love saving bandwidth, Jeroen. I have been
thinking a bit about that:
IPv6 is 128 bits and IPv4 32.
If we used an "ipv4-stylish" allocation plan for ipv6, and dropped the extra
bits we saved by not wasting excessive space, how much money would your
company save ?

Lets say we save 64 bits:
Thats 8 bytes per packet.
256000 pps gives 2048kb per second ~ 20mbit = 800-5000++€ month

If we did, you could get 20mbit free.
But we aren't, so just ignore this.
