APNIC Member Meeting Seoul, Korea, 3 March 2000

APNIC Open Address policy Meeting

Discussion Paper: Proposal for simple assignment procedure of length /29 or longer prefix

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 case when a prefix which is longer than /28. It seems to be reasonable since in case of /29s, three hosts, for example one gateway router and two hosts on the segment, is enough to satisfy the RFC2050 criteria.

Rationale

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

We believe that we are successful for the address space preservation and that this contributes a great reduction of resource for address assignment at JPNIC, LIR and personal end-users as well.
