Address Policy SIG 2002 Sep Proposal for IPv6 Policy for Essential Infrastructure in the AP region Izumi Okutani IP Address Section Japan Network Information Center Copyright (c) 2002 Japan Network Information Center Contents 2 I. Current Status of IPv6 policy II. Comparison of RIR's policy III. Problem with the Current Status IV. Proposed AP policy V. Conclusion Copyright (c) 2002 Japan Network Information Center 3 Current Status of IPv6 policy Joint IPv6 policy by three RIRs were introduced with the principle of consistent policy across the regions June 2002 Joint IPv6 policy completed July 2002 Joint IPv6 policy implemented by all RIRs No Major Problem in Practice Copyright (c) 2002 Japan Network Information Center However… IPv6 policy for “Essential Infrastructure” varies by region Copyright (c) 2002 Japan Network Information Center 5 Definition of Essential Infrastructure Infrastructure considered to be inevitable in the operation of the Internet and those currently specified in ARIN’s microallocation policy Note: Strict definition of the Essential Infrastructure is not in the scope of this presentation Copyright (c) 2002 Japan Network Information Center Comparison of RIR's policy for Essential Infrastructure Root DNS IXP gTLD/ccTLD DNS RIR/IANA APNIC ? /64 ? ?

Copyright (c) 2002 Japan Network Information Center RIPE NCC 7 • Assignment to IXP – May receive address space if meet the definition as IXP – /48 will be assigned as the standard – /64 will be assigned if it will never need more than a single network • Assignment to Root DNS – The same as the size of the minimum allocation to LIRs valid at the time of the assignment – Should not use the address space to provide any services not related to the root server – Assignment must be returned from the organisation if the operational responsibility for a DNS root server move to a new organisation Copyright (c) 2002 Japan Network Information Center ARIN 8 • Defined as a part of micro-allocation policy – IXP, core DNS service providers, RIR and IANA networks – Should be no longer than /48 for IPv6 – Multiple allocations may be granted • Allocation to IXP – allocated from specific blocks reserved only for this purpose – Exchange point operators must provide justification for the allocation • Other micro-allocations – allocated out of other blocks reserved for micro-allocation purposes – a list of the blocks will be publicly available Copyright (c) 2002 Japan Network Information Center APNIC 9 • IXP Assignment – May request an assignment of no longer than a /64 – May make multiple assignments where justified Copyright (c) 2002 Japan Network Information Center Summary of the Comparison 10 • No consistency among RIRs in root DNS and IXP assignments • AP region has no fixed policy except assignments to IXP • ARIN has the most simple policy and easily accommodates unexpected future essential infrastructure • ARIN has covered most types of essential infrastructure Copyright (c) 2002 Japan Network Information Center Problem with the Current Status 11 • “Essential Infrastructure” will receive different assignment size depending on the region • No fixed policy in AP region except IXP assignments Must fix an AP policy for essential infrastructure which is also consistent with other regions Copyright (c) 2002 Japan Network Information Center Proposal: Make AP policy consistent with ARIN APNIC Root DNS ?
