[6bone] Site addressing best practices?

[Aron Silverton]

Does anybody out there have a sample address plan or a document on best 
practices for delegating IPv6 addresses within an ISP or organization?

It looks as though I'm going to be doing some readdressing soon, and I'd 
like to put a nice plan into place.  I'm not too terribly concerned with 
how the bits are doled out - from the left, center, or right - as the 
chances of having to grow a prefix are quite slim.  I'll probably end up 
  not assigning them contiguously just to be sure.

What I am concerned with is how best to use addresses within the /48s 
that I will assign.  This includes address assignments for our main site 
and other internal sites some of which may be tunneled across IPv4 links.

What have people found to be the best way to manage assignments for 
loopbacks, PTP links, multiple subnets of hosts, etc?  I'll probably 
stick with /64s for the PTPs as opposed to /126, /127, or /112.

If I am being too general, let me know and I'll try to post some 
specific questions.

Thanks,

Aron
