What We Know

• RIRs are consistently allocating over 12 /8s each year worldwide

• There are 26 /8s remaining at the IANA as of 30 September 2009

• Demand for IPv4 continues

What Will Happen(in no particular order)

• IPv4 demand continues

• IPv4 free pool depletes

• IPv4 NAT use increases

• IPv6 deployment

The Bottom Line

• We’re running out of IPv4 address space

• IPv6 must be adopted for continued Internet growth

• IPv6 is not backwards compatible with IPv4

• We must maintain IPv4 and IPv6 simultaneously for many years

RIRs have been allocatingIPv6 address space since 1999

Thousands of organizations haveobtained an IPv6 allocation to date

ARIN has IPv6 distribution policies for bothservice providers and end-user

organizations

Situation

Today, the Internet is predominantly based on IPv4

The Internet must run two IP versions at the same time (IPv4 & IPv6) - this is the “dual-stack” approach

10

Page 11: Supernova 2009: John Curran (ARIN) - IPv4 Depletion, IPv6 Adoption

Situation

Today, there are organizations attempting to reach your mail and web servers via IPv6.

In the near future there will be many more deployments using IPv6.

SituationWhat requires contiguous number resources?• Building out major new networks• ISPs adding new customers

What does this mean for:• Enterprise Customers?• Internet Service Providers?• Equipment Vendors?• Content and Hosting Firms?

Call to Action Enterprise Customers

Mail and web servers need to be reachable via IPv6 in addition to IPv4 in the future

Open a dialogue with your Internet Service Provider about future IPv6 services

Each organization’s decision regarding timeline & investment level will vary

13

Page 14: Supernova 2009: John Curran (ARIN) - IPv4 Depletion, IPv6 Adoption

Call to ActionInternet Service Providers

Begin planning to connect customers via both IPv4 and IPv6 now

Communicate with your peers and vendors about IPv6

IPv6 considerations when making purchases

14

Page 15: Supernova 2009: John Curran (ARIN) - IPv4 Depletion, IPv6 Adoption

Call to ActionEquipment Vendors

Probably limited demand for IPv6 in the past

Demand for IPv6 support will become mandatory very, very quickly

Introduce IPv6 support into your product cycle as soon as possible

15

Call to ActionContent Providers

Content clients must be reachable to newer Internet customers

Begin planning to connect hosting customers via both IPv4 and IPv6 now

Encourage customers to use IPv6 and test their applications over it as soon as possible

Government ActionsAwareness

Coordinate with industry

Adopt incentives• Regulatory• Economic

Support and promote activities

Officially adopt IPv6

IPv6 Adoption Needs

IPv6 address space

IPv6 connectivity (native or tunneled)

Operating systems, software, and network management tool upgrades

Router, firewall, and other hardware upgrades

IT staff and customer service training

ARIN Letter to CEOs• Raises awareness of IPv4 depletion

• Encourages active adoption of IPv6

• As of 18 May 2009, ARIN requires that all applications for IPv4 address space include an attestation of accuracy from an officer of the organization
