IPv6 in North America
North American Global IPv6 Summit
June 24-27 2003
Tony Hain
Technology Director - IPv6 Forum Technical Directorate
Technical Leader - Cisco Systems
Introduction
• Perception is that "IPv6 has not taken hold
strongly within North America"
– IPv4 address space is less of a problem there than
the rest of the world
– Private sector requires a business case
• Activities hint at change
– Test beds and early adopters increasing
– Wireless infrastructure emerging
– Industry and Government are looking at the
operational advantages
– Increasing allocation of production global addresses

IP Address Allocation History
1981 - IPv4 protocol published
1985 ~ 1/16 of total space
1990 ~ 1/8 of total space
1995 ~ 1/3 of total space
2000 ~ 1/2 of total space
2002.5 ~ 2/3 of total space
100.00%
90.00%
80.00%
70.00%
60.00%

• This despite increasingly intense conservation efforts
–PPP / DHCP address sharing
–CIDR (classless inter-domain routing)
NAT (network address translation)
plus some address reclamation
• Theoretical limit of 32-bit space: ~4 billion devices
Practical limit of 32-bit space: ~250 million devices (RFC 3194)

Vendor status
• Most networking equipment vendors already
ship IPv6 capable products
• Operating system vendors officially support IPv6
in their latest product releases
• 2003 and beyond: call for APPLICATIONS
– Applications must be IPv4/IPv6 version agnostic
– Successful deployment is driven by applications

Deployment activities
• 6bone R&D network
– 185 sites registered including academia, government, research
labs, vendors, and ISPs
– Planned phase out for cease of operations by July 1, 2006
• Academia & Research communities
– National and regional infrastructures are gradually moving to
dual stacks, & downstream sites are in the planning stages
– International partnerships in process
• Consumer
– Applications and appliances are emerging this year
• Substantial availability over next 18 months

Deployment activities
• Government
– Early adopters running IPv6 networks
– Leading target for IPv6 promotion (NAv6TF) with IPv6 called out
for examination in National Strategy to Secure Cyberspace
– Operational networks require validation process
• Enterprise
– Minimal deployment beyond vendor development networks
– Learning curve in architecture and management groups
– Deployment gated by application and O.S. upgrade strategy

Deployment activities
• Exchange points
– 6tap, 6IIX, NY6IX, PAIX, S-IX(NTT San Jose), …
• ISP
– Plans are largely driven by customer demand
• Lack of explicit demand???
– Trial networks are up and running
• C&W, Hurricane, MCI, Qwest, Sprint, Stealth, Verio, …
– Clear lack of consumer services
• Dial, DSL, Cable, FttH, …
– Return on investment (RoI) justifications sought
• Particularly in the current economic environment

Deployment activities
• Wireless
– U.S. wireless service providers finding it difficult to
create a viable business plan under the limited growth
IPv4 allocation policies
– Some are currently investigating IPv6 as a way
forward, with projected phases of R&D ('03), Trials
('04-05), Production deployment ('06)
– Several 802.11 Hot Spots already offer IPv6
connectivity service

Deployment concerns
• Applications
– Upgrade availability, certification timeframe, …
• Network Management availability
– Provisioning, billing, management stations, operator training, …
• Security
– Maturity of filtering & intrusion detection devices vs. IPv4
– Potential new avenues of attack, and transition interactions
• IPv6 deployment costs & Return on Investment (RoI)
– Software/hardware upgrades, training, …
– Business models for new appliances, applications, and services

Summary
• ARIN is actively allocating IPv6 prefixes
• Deployment activities are quietly underway
• Successful deployment is driven by applications

North-American IPv6 Task Force (NAv6TF)
• Similar in charter to the other IPv6 Forum regional task forces
• Mission: To help promote and foster IPv6 adoption within
target industries through Short & Long Term Objectives
and Deliverables
• Recently, NAv6TF sent its recommendations to the U.S.
President’s Critical Infrastructure Protection Board regarding
the National Strategy to Secure Cyberspace
• Meeting at U.S. Global IPv6 summit – June 2003
• IPv6 Demonstration Collaborative initiative
