And by "stupid addressing scheme" do you mean it's too big, or what? You can ignore all that stuff with mac addresses and make all your addresses go like prefix:subnet::1 prefix:subnet::2 prefix:subnet::3 if you want to.

Screw DNS. Screw the recommendation to stay away from IP's. If it's important enough to be on the network, it's important enough to have a static IP.

Yeah, it works well enough until it doesn't: I love when VoIP calls have one-way audio or when I have to map ports because the traversal method used by this P2P app is not working. When run at the ISP level it's even more fun: remember when wikipedia blocked the whole Qatar?

If your ISP doesn't provide it, get one that does. They should allocate you a /56 by default per connection, if not something larger like a /48 if you have multiple locations.

Subnet the /48 for each connection, subnet each /56 into /64 subnets. reserve one of the /56's for site-to-site if needed.

Done.
