An ISP perspective on IPv6 Deployment

Simon Hackett

Internode

my oldest thing to do
My oldest ‘Thing to do’
  • 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
Customer opinion
  • 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?

in the lab too long
In the lab too long?

“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
Security

“Security considerations are not discussed in this memo”

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

firewalls essential
Firewalls essential

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
The end to end mantra

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
End-to-End examples:

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
None of them work

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
Stopgaps still working

CIDR worked

And IPv6 does not change this

NAT staved off address starvation

Remarkably well

nat not the anti christ
NAT: Not the anti-christ

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
Lack of CPE router IPv6

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
Business Case?

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
Other delay factors

Provider Independent Multihoming broken

Shims and other hacks

Arguments over standardisation further delay deployments

laundry list of other things
Laundry list of other things

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
So what now?

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
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?

otherwise
Its still the best thing we have when IPv4 runs out

(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
So will we deploy?

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
