Hi,
This is proposed for informational, so it won't matter but I'd like to
mention one consideration about address allocations that wasn't mentioned
(perhaps on purpose).
IPv6 address could be summarized by being like 2001:ABCD:OPQR:XYZW::/64.
ABCD is something you can't change (usually).
OPQR is /32 - /48, the range you most often really have to think about.
XYZW is the site internal structure, also subject to some considerations
(a ministrucure of all three, probably).
For _clarity_ (for us hunams :), avoiding overlaps and enabling effective
reverse DNS delations, I personally feel that address
allocations/reservations should be done on the nibble boundary, ie. not
"break a character".
If this nibbles aren't broken (or even if they are), the effective area of
addresses you have is actually rather limited, like CD:OPQR or just OPQR
(or with current RIR scheme, PQR).
