Hi,

2001:db8 came from APNIC, that's why :-) - their delegated file lists

apnic|AU|ipv6|2001:db0::|32|20031112|allocated
apnic|AU|ipv6|2001:dc0::|32|20030124|assigned

so an extention to /29 would technically be possible, to a /28 won't.

As I can't speak for APNIC, this is just about the allocation maths.


Their whois *does* list the prefix, though:

inet6num:       2001:0DB8::/32
netname:        IPV6-DOC-AP
descr:          IPv6 prefix for documentation purpose
...
