IPv4 on life support…
• IANA pool expired in 2011
– RIR regional supplies followed (2012 to 2017)
– Only APNIC has remaining supply (after reclamation in 2023)
• Delaying the inevitable…
– Address sharing, Network Address Translation (NAT), CGNAT
– RIR-registered transfers (sales or leases)
• Trading in the remains…
– Purchase and leasing
– Chaotic white/grey/black markets
– Price: 10 to 1,000x the price of registration

IPv6 address space
• IPv4: 32-bit address
– 232 = 4,294,967,296
– The number of stars in the
observable universe
• IPv6: 128-bit address
– 2128 =
340,282,366,920,938,463,463,3
74,607,431,768,211,456
– Each of those stars contains
an entire IPv4 Internet

IPv6 Drivers
22
22
What drives deployment?
• Motivations
– Supply of addresses: numbering, management, mergers
– Cost of IPv4 (USD $50/address) vs cost of IPv6 (miniscule)
– Cost of IPv4 NAT (USD $40/user/year?) vs no cost for native IPv6
– Efficiency of technology and routing -> Lower latency
– Competition and the network effect
• Doubts
– Human capacity
– Business risks, security and other FUD…
– … natural resistance to change.

Case: Akamai
• All CDN customers receive IPv6
• AbemaTV, Japan (streaming video)
– “…throughput improved by an average of 38% compared to IPv4, and by
67% [during] nighttime”.
• Enterprise adoption is slow but…
– “As Enterprises grow and have acquisitions and different business units,
Private IPv4 space becomes increasingly unwieldy. Using Zero Trust
models with a flat IPv6 global namespace is much easier to manage.” –
Erik Nygren, 2014
26
26
Case: AWS
• Amazon now charges for public IPv4 space
– $0.005/address/hour
– x 24 x 356 = $42 / annum
– IPv6 is now free of charge
• Netflix
– Delivery via IPv6 since 2021
• Business case for IPv6
– “If you don’t have IPv6 on your edge, you’re penalizing your customers”.
– “What I want is a simple flat network that’s just transport, and NATs have
broken that model” – Donavan Fritz, 2021

Follow the leaders
• USA
– DoD and DoC transitions to be completed EOY 2025
• China, Viet Nam
– 100% national deployment by EOY 2025
• Czech Republic
– 100% government services on IPv6 only from 6/6/2032
• India
– All government networks enable IPv6 during 2024

The benefits…
• IP Address supply and cost
• Latency
• Address management
– “set and forget” address planning
– Ready for merger or acquisition
• Future proof
– Growth
– Innovation
– Risk mitigation (IPv4 swamp)
