It seems our counterparts in Asia beleive it's perfectly legitimate
to assign a /48 to a residence... Even in some cases where there may
initialy be only one computer connected.
If we were to mimic their policys, it would seem assigning a /48 per
doorm room, or to the people residing in a doorm room would be perfectly
APNIC IPv6 Guidelines
8.1 Assignment size.
RFC 3177 and the "IPv6 address allocation and assignment policy"
state that a single ends site should ussualy be assigned a /48.
Residential subscribers can receive a /48 when connecting through
on-demand or always-on connections such as ADSL or CATV.
If an end site is expected to grow, an LIR may assign a /48 to
an end site where a /64 or /128 may initially seem more
appropriate (for example an end site with a single computer)
An LIR must submit a second opion request to APNIC if it plans
to assign more then a /48 to an end site (see Section 8.2)
