“A great many stories I can tell you about network operations are not examples
of best practice but more cautionary tales of failures and unintended
consequences.” -- Terry Sweetser
“I have not failed. I’ve just found 10,000 ways
that won’t work.” -- Thomas Edison
Always be learning …

So it started in 2015 …
IPv6?
How hard could that be?

IPv6 Deployment Strategy
Where do you start?
AUDIT
• What is the current state of your
network and what capability
exists to support dual stack?
PLANNING
• Gather your information and
resources before making
decisions. Then DECIDE.
TEAMWORK
• Build your team up with
knowledge and resources: you
will need time and training.
CONSULT
• Talk to managers, executives and
customer experience teams.
More input = more traction.
14

IPv6 Capability Considerations
When we say capable of ipv6, this refers to:
• People
– Engineers, Managers, Helpdesk, Field techs
• Equipment
– Core, Edge and Customer
• Capital
– Human, Financial
• Suppliers of Transit and Peering
– Are they capable?
CPE IPv6 Support is
often overlooked!
15
IPv6 Planning Considerations
• Address Planning
– Number One issue raised time and again!
– “Measure Twice, Cut Once” as renumbering is always painful.
– Be Generous with what you keep in reserve.
– Review it against all progress during deployment.
• Deployment Planning
– You can only start at your border routers, why?
– Pick a service to do first, like DNS or WWW, end-to-end testing.
– Then slowly over Core, Intermediate and then BNG+CPE.
16
IPv4 Depletion: “Blood From A Stone”
• NAT444 aka Double NAT aka The NAT has been NATed.
• NAT64/DNS64, aka “Hey, try this ipv6 address instead.”
• XLAT464 aka “You can’t bypass my NAT64 now.”
• Above will generate end user complaints.
• But you can deploy dual stack alongside above.
• The real solution is “IPv6 before IPv4” and make it stick.
17
IPv4 Depletion …
• The cost of ipv4 is too high.
• Price plateau due to the finding
the maximum willingness-to-pay.
• Capital better spent elsewhere,
even on LSN and CGN hardware.
Market Signal:
• A price drop means IPv6 has
“won the deployment war” and no
one (sensible) is buying it.

and 2022 (data by IPv4.Global)

Terry Says
“If you have not talked to everyone about your big
technical plan for ipv6, you have not done enough
consultation.” – Terry Sweetser
“Move fast and break things.” – Mark Zuckerberg until 2014 ☺
“Prototype and test things in a lab, better to set that on
fire than your production network!” – Terry Sweetser

LKNOG6 IPv6 Implementation Stories and Where to Start presentation by Terry Sweetser for LkNOG 6

  • 1. 1
  • 2. 2 IPv6 Deployment My Stories Hard Lessons IPv6 Deployment Strategy APNIC Academy
  • 3. 3 Terry Sweetser Been doing this “Internet thing” since 1989. Former APNIC Community Trainer, CTO, Founder, Engineering Manager, etc APNIC Training Delivery Manager for South Asia and Oceania Nationality: Australian Languages: English about.me/terry.sweetser
  • 4. 4 “A great many stories I can tell you about network operations are not examples of best practice but more cautionary tales of failures and unintended consequences.” -- Terry Sweetser “I have not failed. I’ve just found 10,000 ways that won’t work.” -- Thomas Edison Always be learning …
  • 5. 5 So it started in 2015 … IPv6? How hard could that be? Note: all data sources are APNIC unless otherwise stated.
  • 7. 7 7 Oh, 13.44% at 22 November 2016
  • 9. 9 9 AS1221 “Catch Them If You Can”

  • 13. 13 IPv6 Deployment Strategy Where do you start? AUDIT • What is the current state of your network and what capability exists to support dual stack? PLANNING • Gather your information and resources before making decisions. Then DECIDE. TEAMWORK • Build your team up with knowledge and resources: you will need time and training. CONSULT • Talk to managers, executives and customer experience teams. More input = more traction.
  • 14. 14 14 IPv6 Capability Considerations When we say capable of ipv6, this refers to: • People – Engineers, Managers, Helpdesk, Field techs • Equipment – Core, Edge and Customer • Capital – Human, Financial • Suppliers of Transit and Peering – Are they capable? CPE IPv6 Support is often overlooked!
  • 15. 15 IPv6 Planning Considerations • Address Planning – Number One issue raised time and again! – “Measure Twice, Cut Once” as renumbering is always painful. – Be Generous with what you keep in reserve. – Review it against all progress during deployment. • Deployment Planning – You can only start at your border routers, why? – Pick a service to do first, like DNS or WWW, end-to-end testing. – Then slowly over Core, Intermediate and then BNG+CPE.
  • 16. 16 IPv4 Depletion: “Blood From A Stone” • NAT444 aka Double NAT aka The NAT has been NATed. • NAT64/DNS64, aka “Hey, try this ipv6 address instead.” • XLAT464 aka “You can’t bypass my NAT64 now.” • Above will generate end user complaints. • But you can deploy dual stack alongside above. • The real solution is “IPv6 before IPv4” and make it stick.
  • 17. 17 IPv4 Depletion … • The cost of ipv4 is too high. • Price plateau due to the finding the maximum willingness-to-pay. • Capital better spent elsewhere, even on LSN and CGN hardware. Market Signal: • A price drop means IPv6 has “won the deployment war” and no one (sensible) is buying it. IPv4 price history between 2014 and 2022 (data by IPv4.Global) Source: https://www.ipxo.com/blog/ipv4-price-history/
  • 18. 18 Terry Says “If you have not talked to everyone about your big technical plan for ipv6, you have not done enough consultation.” – Terry Sweetser “Move fast and break things.” – Mark Zuckerberg until 2014 ☺ “Prototype and test things in a lab, better to set that on fire than your production network!” – Terry Sweetser
