Your own IPv6 /64 block?

general

Soon, Linode will begin handing out /64 blocks for free.

Each /64 block is 18,446,744,073,709,551,616 IPv6 addresses.

There are 18,446,744,073,709,551,616 /64 blocks in the IPv6 pool.

This is 4,294,967,296 times the number of total single IPv4 addresses.

I plan to acquire a /64 block of IPv6 addresses when they become available.

I don't have plans for any of them.

So I'm wondering, what could I possibly do with an entire /64 block? What could I use it for? They're being handed out like candy on Halloween. What's the big deal?

Bragging rights! You can brag to your buddies that you have more IPv6 Addresses than they do!.

But then your buddies can get a /48 from 6to4 or HE. :X

Edit: More on-topic, I like having 32 bits to work with so I can create more meaningful addresses, e.g. "2001:db8:1:2::443:1" for an HTTPS site. Aside from EUI-64, I have no idea what to do with a full 64 bits, though. In fact, I can't decide whether to use "2001:db8:1:2:443::1" or "2001:db8:1:2::443:1", and have switched back and forth once or twice.

Edit: Typo.

Hrmm then you'd have to get a /48 AND a /64!
