      Thank you very much for editing the draft. I think it is compiled in
      such a way to get across the points listed by the WG clearly.
      
      I just have one comment and a question regarding the DB registration.
      
      --------------------------------------------------------------------------
       11 	Registration requirements
       ---------------------------------
      (snip)
       	* Assignments for networks of /48 or less may be registered, at
       	  the discretion of the LIR and the network administrator.
       	* Assignments to hosts may be registered, at the discretion of
       	  the LIR and the end site.
      --------------------------------------------------------------------------
      
      It is stated that assignments longer than /48 can be registered. Would
      such registrations be taken into account when calculating the
      utilization?
      
      If the answer is yes, I am not sure if the needs for the registrations
      are strong enough, especially registering assignments in host basis,
      while adding complications to the policy as well as the registry
      database.
      
      
      
      Best Regards,
      Izumi

      > 	Multiple sites
      > 	
      > 	* A home or corporate user who has multiple contracts with one

      > 11 	Registration requirements
      > ---------------------------------
      > 
      > LIRs are responsible for promptly and accurately registering their
      > allocations, sub-allocations, and assignments in the APNIC Whois
      > Database, as follows:
      > 
      > 	* All allocations and sub-allocations must be registered.
      > 	* Assignments for networks greater than /48 must be registered.
      > 	* Assignments for networks of /48 or less may be registered, at
      > 	  the discretion of the LIR and the network administrator.
      > 	* Assignments to hosts may be registered, at the discretion of
      > 	  the LIR and the end site.
      > 	
      > When an LIR makes a sub-allocation to a downstream ISP, the LIR is
      > responsible for ensuring that assignments from the sub-allocated range
      > are registered in the database; however, the LIR may delegate the
      > responsibility to the downstream ISP.
      > 
      > Note: Privacy of customer assignments (prop-007-v001) will be
      > implemented in 2004. This new policy no longer requires the
      > registration of assignments and sub-allocations to be publicly
      > available. The registration of customer assignments is still required,
      > but will be 'hidden' by default.
      > 
      > 
      > 11.1 	Updating registration details
      > 
      > 	LIRs must update the APNIC Whois Database when any of the
      > 	registration information changes. This is the responsibility of
      > 	the LIR concerned, but may be formally delegated to the end
      > 	user as a condition of the original assignment.
      > 
      > 
      > 11.2 	Registering contact persons
      > 
      > 	Administrative and technical contact persons must be registered
      > 	.
      > 	The registered administrative contact (admin-c) must be someone
      > 	who is physically located at the site of the network, subject
      > 	to the following exceptions:
      > 	
      > 	* For residential networks or users, the network's technical
      > 	  contact may be registered as admin-c.
      > 	* For networks in exceptional circumstances that make it
      > 	  impractical to maintain an on-site administrative contact, an
      > 	  off-site person may be registered as the admin-c.
      > 	
      > 	The technical contact (tech-c) need not be physically located
      > 	at the site of the network, but must be a person who is
      > 	responsible for the day-to-day operation of the network.
