An ISP perspective on IPv6 Deployment

My oldest thing to do l.jpg
My oldest ‘Thing to do’ which will create action items. Use PowerPoint to keep track of these action items during your presentation

  • I have wanted to deploy IPv6 for a long time

  • We’ll talk about the barriers to that, for an ISP

  • But first…


Customer opinion l.jpg
Customer opinion which will create action items. Use PowerPoint to keep track of these action items during your presentation

  • What do our customers think about:

    • The need to transition to IPv6 to avoid IP address exhaustion?

    • The importance of the restoration of a true end to end IP Internet without NAT gateways?

    • The importance of IPv6 in their lives?


Status of ipv6 l.jpg
Status of IPv6 which will create action items. Use PowerPoint to keep track of these action items during your presentation

"With the protocol mostly nailed down, the doors are open for rapid implementation and deployment by vendors"

In the lab too long l.jpg
In the lab too long? which will create action items. Use PowerPoint to keep track of these action items during your presentation

“There is never time to do it right, but always time to do it over”

Critical items not resolved for many years have damaged the credibility of IPv6 deployment


Security l.jpg
Security which will create action items. Use PowerPoint to keep track of these action items during your presentation

“Security considerations are not discussed in this memo”

Lack of an end to end security architecture has further driven firewalls and NAT


Firewalls essential l.jpg
Firewalls essential which will create action items. Use PowerPoint to keep track of these action items during your presentation

In the real world, the only thing stopping massive customer PC collapse is firewalls and NAT

The costs of removing them would be massive

Edge node security in the real world is really bad


The end to end mantra l.jpg
The end to end mantra which will create action items. Use PowerPoint to keep track of these action items during your presentation

In 1995 we wanted to preserve end-to-end connectivity

In 2006, the king is dead - long live the king

In the real world:

Customers do not want end to end, they want to be firewalled

And ISPs agree with them


End to end examples l.jpg
End-to-End examples: which will create action items. Use PowerPoint to keep track of these action items during your presentation

Soldiers with LANs in their backpacks within a battlefield IPv6 network

Windscreen wipers on all the cabs in Tokyo

Massive sensor networks

Every single customer PC in Australia


None of them work l.jpg
None of them work which will create action items. Use PowerPoint to keep track of these action items during your presentation

None of them should be ‘public’ at all!

All require security to firewall them, and are likely to use a server to securely/safely mediate access to summary data

So what was that about end to end again?


Stopgaps still working l.jpg
Stopgaps still working which will create action items. Use PowerPoint to keep track of these action items during your presentation

CIDR worked

And IPv6 does not change this

NAT staved off address starvation

Remarkably well


Nat not the anti christ l.jpg
NAT: Not the anti-christ which will create action items. Use PowerPoint to keep track of these action items during your presentation

NAT and firewalls are the real world

Society employs them in many realms

They have naturally entered this one

IETF negativity toward NAT standardisation has raised to cost of NAT and increased interworking faults

But it works anyway


Lack of cpe router ipv6 l.jpg
Lack of CPE router IPv6 which will create action items. Use PowerPoint to keep track of these action items during your presentation

Almost zero consumer broadband CPE deployment of IPv6

Critical barrier in real world consumer networks

Blocks end-to-end even if desired

Difficult to see these devices ceasing to use NAT/Firewalls due to inherent benefits in doing so


Business case l.jpg
Business Case? which will create action items. Use PowerPoint to keep track of these action items during your presentation

There is no compelling ISP business case

Commercial premium for IPv6 is zero

IPv6 not essential for any application

There is no nett positive income to gain, its just infrastructure change after all

True end to end distributes the security problem in a currently un-tenable manner

No current crisis to force the issue


Other delay factors l.jpg
Other delay factors which will create action items. Use PowerPoint to keep track of these action items during your presentation

Provider Independent Multihoming broken

Shims and other hacks

Arguments over standardisation further delay deployments


Laundry list of other things l.jpg
Laundry list of other things which will create action items. Use PowerPoint to keep track of these action items during your presentation

Other challenges abound, to further obstruct progress to IPv6:

dual-stacking challenges; non-optimised router code; apathy; security challenges; customer support; DNS infrastructure challenges; ISP resource requirements (network operations, technical support)


So what now l.jpg
So what now? which will create action items. Use PowerPoint to keep track of these action items during your presentation

Keep improving IPv4

This will keep happening anyway.

Do keep advancing IPv6 ready for the crunch when it finally happens

Secondary stopgap:

Two-stage NAT on customer dynamic IP populations would massively lower IPv4 demand

“I cant believe its not the Internet”

Static IP customers exempted but charged more for requiring end-to-end

No current premium on external static IPs


Tradeable ipv4 addressing l.jpg

Create an economy around IPv4 IP ranges to force the crunch earlier:

Sell new, and trade old, IPv4 address ranges

As for Carbon tax/Carbon Credit economy

Zero-rate IPv6 addresses for a ‘long’ time

Create economic drivers to achieve result needed

Donate new direct NIC income stream into Carbon Credits!

Tradeable IPv4 Addressing?

Tradeable IPv4 Addressing?


Otherwise l.jpg

Its still the best thing we have when IPv4 runs out earlier:

(still!) a question of when

Without economic drivers or customer demand…?

People are very bad at caring in the absence of crisis

Otherwise?


So will we deploy l.jpg
So will we deploy? earlier:

Yes, we will

It remains, however, a difficult question of when

I really, really want to do it

It has, somehow, to get above the noise floor

It has, somehow, not to represent a major technical cost to deploy, or:

Tradeable IPv4 addresses may force the issue on an economic basis ‘underneath’ customers in a network transparent manner
