APNIC received the following IPv4 address blocks from IANA in February 2011 and will be making allocations from these ranges in the near future: 39/8 106/8 Reachability and routability testing of the new prefixes will commence soon. The daily report will be published at the usual URL: http://www.ris.ripe.net/debogon Please be aware, this will be the final allocation made by IANA under the current framework and will trigger the final distribution of five /8 blocks, one to each RIR under the agreed "Global policy for the allocation of the remaining IPv4 address space". http://www.icann.org/en/general/allocation-remaining-ipv4-space.htm After these final allocations, each RIR will continue to make allocations according to their own established policies. APNIC expects normal allocations to continue for a further three to six months. After this time, APNIC will continue to make small allocations from the last /8 block, guided by section 9.10 in "Policies for IPv4 address space management in the Asia Pacific region". This policy ensures that IPv4 address space is available for IPv6 transition. http://www.apnic.net/policy/add-manage-policy It is expected that these allocations will continue for at least another five years. APNIC reiterates that IPv6 is the only means available for the sustained ongoing growth of the Internet, and urges all members of the Internet industry to move quickly towards its deployment.

This means that only five /8s of IPv4 address space are left in the IANA free pool and the "Global Policy for the Allocation of the Remaining IPv4 Address Space" will be triggered. This policy can be found online at: http://www.icann.org/en/general/allocation-remaining-ipv4-space.htm When this policy comes into effect, the five RIRs will each receive one of the five remaining /8s and the global IPv4 pool will be exhausted. We expect IANA to allocate these final /8s within the next few days.

As you may have noticed the IPv6 working group is missing from the meeting plan. This is not an error, but an intentional change to the agenda. After some discussion with the working group chairs collective and other stakeholders, we concluded that the IPv4 run out and the associated need to deploy IPv6 will most likely be a very hot topic on this upcoming meeting. It has therefor been decided that the time originally allocated for our working group would be added to the plenary program. Any interesting IPv6 topics, and I'm sure there are many, will be placed in the plenary schedule. At the same time, the closing plenary on Friday morning will host a "IPv6 roundup". In this session we will discuss the outcome of the meeting, based on input received from the working groups and presentations or comments during the plenary sessions. In other words, no need to panic. The IPv6 working group will be present, although not in a formal setting this time. If you have any interesting information on IPv6 deployment, interactions between IPv4 and IPv6 and deployment of transitioning techniques. Please consider presenting about it on this meeting and send a short description of what you like to present together with your contact details to ipv6-wg-chairs at ripe dot net. See you in Amsterdam, The IPv6 working group chairs, Marco, Shane and David.

Best regards, Rob -------- Original Message -------- Subject: [routing-wg] IPv6 Routing Recommendations. Date: Wed, 23 Feb 2011 14:39:18 +0800 From: Rob Evans To: routing-wg at ripe.net All, You may remember that back in the mists of time (about a year ago) we had a document that updated RIPE-399 with some IPv6 routing recommendations. After the meeting last May, the authors were to go away and take out mention of any specific suggestions on filtering (e.g. /36). Over the past 12 months, Philip and I have been hard at work constantly refining this document to reflect the changing nature of the IPv6 routing table. Well, kind-of. Anyway, my laziness aside, appended is the document as it stands at the moment. Comments and discussion please! Rob RIPE Routing Working Group Recommendations on IPv6 Route Aggregation ==================================================================== Rob Evans Philip Smith Introduction ============ Recent discussion has shown there is a limited requirement to be able to advertise more specific prefixes from an IPv6 Provider Aggregatable (PA) allocation where a Local Internet Registry (LIR) contains several networks which are not interconnected, or for traffic engineering purposes. This document recommends such advertisements are limited in both length and scope. It is intended to supplement the working group's Recommendations on Route Aggregation [RIPE-399]. Background ========== The IPv6 address allocation and assignment policy for the RIPE region [V6-ALLOC] only allows LIRs to obtain more than the minimum PA allocation if they can demonstrate address utilisation that requires it. This fits with the address space management principle of conservation. However, as understood in the RIPE Routing Working Group's Recommendations on Route Aggregation [RIPE-399], there are occasionally requirements for the advertisement of more specific routes from within an allocation. With a few ISPs currently filtering at the minimum PA allocation (/32) within the relevant address ranges, this can cause significant difficulties for some networks wishing to deploy IPv6. Some reasons for wanting to advertise multiple prefixes from a PA allocation could be: - The LIR has several networks that are not interconnected. - Traffic engineering: A single prefix that covers an LIR's entire customer base may attract too much traffic over a single peering link This document is only concerned with IPv6 Provider Aggregatable (PA) allocations, and does not discuss Provider Independent (PI) prefixes. Recommendation ============== It is suggested that prefix filters allow for prudent subdivision of an IPv6 allocation. The operator community will ultimately decide what degree of subdivision is supportable, but the majority of ISPs accept prefixes up to a length of /48 within PA space. Advertisement of more specific prefixes should not be used unless absolutely necessary and, where sensible, a covering aggregate should also be advertised. Further, LIRs should use BGP methods such as NO_EXPORT [RFC-1997], [AS-PATHLIMIT], or provider-specific communities, as described in [RIPE-399] to limit the propagation of more specific prefixes in the routing table. Discussion ========== There is a valid need for some LIRs to advertise more than one IPv6 PA prefix. As either obtaining more address space and advertising more /32 prefixes, or advertising more specific prefixes within an already allocated /32 have the same impact on the routing table, it is suggested that the latter approach is taken to prevent address space wastage. It is understood that this may not cover all possibilities. There may be circumstances where sites will have to consider the suitability of Provider Independent addresses, or LIRs may have to consider mechanisms of obtaining more than a /32 of Provider Aggregatable space.

Reason is TSP doesn't embed the customer's IPv4 address in its IPv6 address as 6RD does. Being a hot topic nowadays, its worth mentioning customer site access gear (CPE) requirements are more relaxed with TSP as it doesn't need the Service Provider IPv4-only access modem to be changed or upgraded. A TSP client can run in a small hardware device (thru an Ethernet interface connection) or a software client in the home network behind the SP modem while enabling all v6 capable nodes with the assigned prefix by automatically establishing a tunnel to the SP TSP tunnel server. Since TSP allows for static prefix assignment and larger prefixes than /64 without wasting v6 space, this would mimic a native deployment more closely. The stateful tunneling could be seen as any other encapsulation in the access, and a few service providers have it running already. In the long term, both 6RD and TSP will give way to reverse tunneling i.e. v4-in-v6, as this is the only way (after IPv4 depletion) for both protocols to co-exist on a host while having a mix of v4-only and dual-stack accessible services/website. Reverse tunneling's current protocols, DS-Lite and DSTM, are very similar to TSP's concept so the same clients & servers supporting TSP can be adapted to support DS-Lite. Unfortunately, until IPv4 disappears from web content, hosts and servers these coexistence mechanisms will be needed. Regards, -Ahmed From: Kurt Smolderen Sent: Monday, February 28, 2011 11:13 AM To: address-policy-wg at ripe.net Subject: RE: [address-policy-wg] IPv6 allocations for 6RD I strongly support the idea of assigning a smaller prefix to ISPs which are in a state of deploying IPv6 but need to use transitional mechanism for (some of) their customers. Mark has described one of the problems very clear in his email: if an ISP has only a /32 prefix and needs to use all 32 IPv4 bits in the 6rd configuration, only a /64 can be delivered to the home instead of the desired /56 or /48. Needing all 32 bits is for instance the case when an ISP offers internet connectivity to some of its customers via a partnership with another ISP. However, I want to point to an additional problem which appears when an ISP wants to deploy native IPv6 but needs to roll out 6rd (or any other transitional technique) as well. For native IPv6, the ISP will create an IPv6 addressing plan. This will normally include separate prefixes for the ISP's own servers, the ISP's backbone, the ISP's customers etc. For the 6rd domain, the full /32 range is however needed. So at this stage, the ISP has two options: 1) Implement 6rd only 2) Implement native IPv6 only and exclude some customers from being able to use IPv6 (those which would normally be connected through 6rd) I strongly believe we all agree 6rd is only a temporary solution. So I can't imagine we would prefer skipping native IPv6 deployments in favor of IPv6 transitional mechanisms. I also believe we all agree we should enable IPv6 for as much customers as we can, which makes me conclude the second 'option' is not really an option at all... My primary concern is that any ISP - regardless of how small or big it is - can independently of other organizations/ ISPs move forward with IPv6 deployment. RIPE can support this by adapting a policy which - albeit for a limited time span - allows the assignment of a contiguous IPv6 prefix which size does not only depend on the amount of customers the ISP has, but also incorporates the needed technologies to 'IPv6-enable' as much customers as possible.

Reason is TSP doesn't embed the customer's IPv4 address in its IPv6 address as 6RD does. TSP is stateful, and thus scales in proportion to the number of subscriber endpoints supported as opposed to simply the number of IPv6 packets transported (e.g., TSP servers will likely have a "per-user" license or at least a per-user scaling limit per box. In contrast, 6rd has no concept of the number of users it is supporting, only the number of packets it is pushing). - Mark > > Being a hot topic nowadays, its worth mentioning customer site access gear (CPE) requirements are more relaxed with TSP as it doesn't need the Service Provider IPv4-only access modem to be changed or upgraded.
