14. http://www.ripe.net RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb 2007 14 Arno Meulenkamp IPv6 Allocation Criteria You - are an LIR - not an End Site - plan to provide IPv6 connectivity to aggregated ‘customers’, who are assigned /48s - plan to assign 200 /48s within two years Minimum initial allocation size /32 - more if needed, calculated with HD ratio 602 Allocations, 4000+ Members!

15. http://www.ripe.net RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb 2007 15 Arno Meulenkamp IPv6 Assignment and Utilisation Requirements (2005-08) Aims to increase the useful lifetime of IPv6 - period in excess of 100 years - no further allocation policy changes are anticipated Changes: - allow assignment size to be chosen by LIR - “End Site” definition for HD ratio calculation to /56 - HD ratio from 0.8 to 0.94 /32 Allocation: - old: HD ratio 0.8, /48 assignments: 7132 /48s needed (11%) - new: HD ratio 0.94, /56 assignments: 6,183,533 /56s needed (37%) (24,154 /48s)

16. http://www.ripe.net RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb 2007 16 Arno Meulenkamp Provider Independent (PI) IPv6 Assignments for End User Organisations (2006-01) Currently: - No PI in IPv6 - Only possible to multihome with LIR allocation - Multihoming a requirement for some non-LIR organisations Temporary policy: until three years after technical alternative is available

17. http://www.ripe.net RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb 2007 17 Arno Meulenkamp IPv6 Address Allocation and Assignment Policy (2006-02) Changes to the policy: - organisations without external customers can also qualify - allow assignment size to be chosen by LIR - remove “plan for 200 assignments”
