IPv6 deployment updates

Geoff Huston has published an update on IPv6 deployment that contains some interesting details.

  • With an estimated 10 billion devices on the Internet today, they are sharing about 1-2 billion of the 4 billion possible IPv4 addresses.  Using those numbers the Internet today is about 10 times larger than the amount of address space being used to actually communicate between clients.
  • Mobile networks such as T-mobile using 464-XLAT are driving IPv6 traffic.  (copy)
  • Belgium leads in IPv6 deployment by percentage followed by the United States.

ARIN 35 Public Policy Preview

ARIN35Next week is the ARIN 35 meeting in San Francisco.   Here is my look ahead at the some of the nine policies being discussed at the meetings.  There are four recommended draft that will be discussed along with lots of other items on our agenda.  If you aren’t going to be there in person check out the remote participation options.

2014-1 Out of Region Use

Policy Summary: This recommended draft policy allows organizations which have a small block in the region to request resources for use outside of the region.

Discussion: This policy started after it became known that organizations which are generally outside the region were requesting resources and using them almost exclusively outside the region.  The primary motivation for these companies is that IPv4 has already been depleted at other RIRs.  The policy took a number of twists and turns, but in general the community would like to see organizations which are headquartered in the region to be able to get addresses for all of their networks globally.  While this seems simple reducing this to policy has been a challenge.

The policy as currently drafted only requires a small nexus of addresses in the region /22 of IPv4, /44 of IPv6, or 1 ASN.  ARIN’s legal counsel has raised strong concerns regarding this policy and those concerns will likely be the root of the discussion at the meeting.

2014-6 Remove Operational Reverse DNS Text

Policy Summary: This recommended draft policy removes text in the number policy manual which defines ARIN’s operational practice with regard to reverse DNS records.

Discussion: The purpose of this policy is to remove text out of the policy manual which is operational in nature rather than number policy.  It is planned that this operational policy be moved to other locations where it can be updated as needed by ARIN’s operational staff, rather than the number resource community.

2014-14 Remove Needs Test on Small Transfers

2014-14 Policy Summary: This draft policy removes needs testing from blocks which are smaller than /20 and permits an organization to have one needs-free transfer per year as long as a corporate officer attests to the organizations need of the addresses.

Discussion: This policy was rewritten extensively, largely by myself, with input from members of the AC.  When the policy was returned to the list the new text seems to have fallen flat without much discussion.  In my mind this means I have crafted text that now appeals to very few because it makes great compromises between the two sides of the argument for and against needs testing in the transfer market, or people don’t think this type of policy will solve the problems that exist in the current transfer market.  I suspect this policy will likely be abandoned by the AC following the meeting.  Hopefully, at least we have a robust discussion about what types of policy changes are needed as ARIN moves to mostly processing transfers rather than issuing addresses from the IPv4 free pool.

2014-21 Modification to CI pool

Policy Summary: This recommended draft policy sets asside an additional /16 for use by critical infrastructure.

Discussion: The policy is intended to benefit the  Internet exchange point community, which is rapidly changing in the region.  Given the imminent run-out of IPv4 free pool in the ARIN region, this policy is intended to insure that exchange points will have the number resources they need to continue to expand and provide needed interchange services for years to come.

2014-22 Removal of Minimum in Section 4.10

Policy Summary: This recommended draft policy changes the minimum block size from /28 to /24 for the IPv6 transition block.

Discussion: This policy increases the minimum block size because recent testing has noted that smaller blocks may not be routable.  This is, in my opinion, a chicken and egg, problem.  People aren’t accepting smaller blocks because there aren’t many of them now, and they haven’t really been issued by the registries to entities which have the ability to get them routed.  Others believe that the /24 boundary is so engrained in the operator community that they won’t change thus making smaller blocks basically useless to organizations which receive them.  I suspect that the larger ISPs and providers will support this change as it allows them to maintain the status quo rather than changing to support the changing network environment.

2015-1 Change in IPv6 End-User Assignment criteria

Policy Summary: This draft policy changes the assignment rules for small organizations.

Discussion: It was pointed out recently that a type of small organization currently cannot receive an IPv6 assignment because the criteria is too strict.  Furthermore, it is noted that renumbering is a complicated and costly process and these small organizations would not like to have to take on the renumbering process when they change providers.

IP addresses in 2014

Geoff Huston has posted his 2014 version of his IP addressing report.  A few notes from within the report.

  •  Cisco, Morgan Stanely, & Gartner predicted that by 2020 there will be between 25 – 75 billion devices on the Internet as the “Internet of things” comes to life with embedded devices all requiring connections.
  • LacNIC, RIPE, and APNIC’s austerity address pools are slated to be depleted between 2017-2021 if current trends continue to hold.
  • IPv4 transfers increased quite dramatically in 2014 with APNIC performing 340 a 220% increase, and RIPE 919 a 600% increase.  RIPE’s increasing transfers seem to be clearly being driven by the lack of needs-basis requirements in the region.
  • LacNIC and RIPE continue to lead the world in IPv6 allocations with 1,208 and 2,218 respectively.

Measuring IPv6 Adoption

A new look on IPv6 adoption data was recently presented at the SIGCOMM conference in Chicago.  The research, which was a collaboration between multiple groups, looks at over a decade of IPv6 data and notes that some measurements have seen a 400% increase in IPv6 traffic between 2012 and 2013.  The data also shows a significant shift in the type of data toward HTTP & HTTPS content by end-users rather than server to server communication which was observed in earlier in the deployment timeline.

Routing table growth causes some hiccups

News reports have been circulating over the past couple of days that various service providers have hit the 512k route mark in their BGP tables on their routers and switches causing outages and other problems.  A number of hardware platforms, notably older Cisco hardware, have default limits in their configurations which limit route tables sizes to 512k routes.  When these limits are breached the older hardware slows down or otherwise stop functioning as expected. Cisco issued a bulletin in May to providers with workaround procedures for some platforms.

The growth in the global route table has been fairly stable over the past couple of years and this is growth has been expected for a long time and yet still Internet service providers were not prepared in time for this event.
