RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp Abstract The Numbers - IPv4 - ASN - IPv6 The Policies - IPv6

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp Introduction To The Numbers: IPv4 A “/8” is 16,777,216 addresses There are 256 * /8s Minimum allocation to LIRs: / addresses

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp Introduction To The Numbers: IPv6 Millions of times more addresses! - When compared to IPv4 Focus is more on networks - Not individual addresses

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp Introduction To The Numbers: ASN Autonomous System Numbers - Routing Identifier Initially 65,536 ASNs available Now billions more: ASN32 - Introduction phase until Available from 1 January 2007

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp IPv6 Allocation Policies Current policy Policy proposals

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb 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, Members!

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp IPv6 Assignment and Utilisation Requirements ( ) 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)

RIPE Network Coordination Centre ISOC 2007/IPv6 Forum, Tel Aviv, Feb Arno Meulenkamp Provider Independent (PI) IPv6 Assignments for End User Organisations ( ) 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

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