The case for IPv6 is not the same as that for IPv4. 

In the case for IPv4, APNIC allocates IPv4 address blocks and
delegates the reverse lookup function to JPNIC, for example. So, an
ISP in Japan requests an IPv4 address block to JPNIC then JPNIC
assigns an block to the ISP. When ISP updates the JPNIC DB, it is
JPNIC that sets up reverse lookup for the ISP's customer. This seems
to work well since JPNIC handles both IPv4 address assignments and
reverse lookup.

However, in the case for IPv6, it is APNIC that allocates an IPv6 sTLA
to an ISP in Japan. When the ISP sets up reverse lookup for customers
by himself, how to ensure to make the ISP update the *APNIC* DB? 

In this case, who has responsibility to encourage ISPs to update the
APNIC DB?
