Title: Proposal for simple assignment procedure of length /29 or 
        longer prefix
Applicant: Yoshiyuki Ezura, IP working group, JPNIC


- Introduction

RFC2050 and APNIC's policy define that ISP's customers must exhibit 
very precise projection for their one year address usages and the 
justifications for it.  This rule is even applied to the prefix which 
is /29 or /30. 

/29s and /30s are widely used in Japan by personal users now, which 
costs too much for both the applicants and Internet Registry. It may 
impede the sound growth of the Internet.


- Proposal

We propose a simple procedure in which applicants don't need the 
network detail information in the case when a prefix is longer than 
/28. It seems to be reasonable since in the case of /29s, three hosts, 
for example one gateway router and two hosts on the segment, is 
enough to satisfy the RFC2050 criteria.


- Reasons or Advantages

We at JPNIC held a trial operation from March 1998 until January 2000, 
that didn't require the network detail information in the case of when 
assigning /29 and longer, to encourage assignment of longer prefixes 
and preservation of the IP address space. Now in Japan, 41% of all 
assignments is /29 and longer and 87% is /28 and longer.

We believe that trial operation was successful in address space 
preservation and that this contributes a great reduction in resources 
needed for address assignment at JPNIC, LIR and personal end-users as well.
