It seems that someone in ARIN land believes that IPv6 addresses are scarce resources that need to be carefully dribbled out to customers according to need. The following proposal has just been formally made to change ARIN's allocation policy. ------start of copied text------ Replace the text in section 6.5.4.1 with the following text: LIR's may assign blocks in the range of /48 to /64 to end sites. All assignments made by LIR's should meet a minimum HD-Ratio of .25. * /64 - Site needing only a single subnet. * /60 - Site with 2-3 subnets initially. * /56 - Site with 4-7 subnets initially. * /52 - Site with 8-15 subnets initially. * /48 - Site with 16+ subnets initially. For end sites to whom reverse DNS will be delegated, the LIR/ISP should consider making an assignment on a nibble (4-bit) boundary to simplify reverse lookup delegation. LIR's do not need to issue all 5 sizes of prefixes as long as the HD-Ratio requirement is met. ------end of copied text------ --Michael Dillon _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
