Getting Serious About IPv6

Why you need to pay attention

to IPv6… now

In less than a year ARIN runs

out of IPv4 addresses

So what?

This is what everyone talks

about – there are no more IPv4

addresses!

Honestly, this isn’t why you

need to pay attention to IPv6

The real reason you need to

pay attention?

You already deployed IPv6...

you just didn’t know it

For the majority of current OS flavors

IPv6 is enabled and on by

default

IPv6 is preferred

There are IPv6 transition

technologies in Windows

There is zeroconf

capabilities in all the OS’s

using IPv6

There are mDNS or

LLMNR capabilities using

IPv6

IPv6 & IPv4 on the same

OS is called dual-stack

IPv6 configures link-local

address automatically

IPv6 will connect with link-

local

IPv6 will dynamically build

addresses

IPv6 has several address

mechanisms – does your

team know them?

For Windows…

IPv6 transition

technologies are on by

default

If you deployed Windows

Vista, 7, 8 or Server 2008,

2008R2, 2012 or 2012R2,

congratulations!...

…You deployed IPv6, you

just didn’t do any planning

Do you understand the

impact of turning IPv6 off?

Do you understand the

impact of turning off IPv6

transition technologies?

Is your staff educated

enough to know how to do

either?

Does your company have compliance

requirements?

So… how do you pass a

compliance audit when you

have a protocol running on

your network you don’t

understand?

How educated is your staff

on understanding IPv6?

Would they know it if they

saw it?

Even if you think you have

turned IPv6 off on your

equipment, how often do

you actually audit and

check to see if it is

running?

Do you perform network

captures to understand

what is or is not using

IPv6?

Did you pause at all and think…

It is easier to adopt and

support IPv6 then to run away

from or ignore it

It is less expensive in the long

run too

Because…

You will have purchased

the right equipment to

support IPv6 the first time

Your staff has the

knowledge to manage and

mitigate any issues with

IPv6 (avoiding downtime)

You have less concerns

around compliance

You understand how your

applications and services

work over IPv6

Deploying new OS’s with

IPv6 support are not as

difficult

Impact if I only stay on IPv4

The transition is going to be ugly, for everyone

For service providers, they

are starting to adopt and

deploy IPv6

But…

They need to extend the

life of IPv4 due to the slow

adoption of IPv6

They do this with Carrier

Grade NAT or CGN

But…

CGN breaks IPv4

uniqueness

CGN exasperates IPv4

port exhaustion issues

CGN compounds stateful

NAT issues

Your users will start experiencing things like:

http://isoc.org/wp/ietfjournal/?p=262

What problems will my company see?

First, it will be much harder

for your employees to get

public IPv4 addresses at

home (DSL or Cable)

This will cause problems

for VPN, VoIP, Video and

Collaboration depending

on how they are deployed

Second, as partners, 3rd

parties and employees

start getting IPv6 and you

stay on IPv4, their

connection will be proxied

to you

Because these sessions

are proxied, you lose the

ability to have end to end

connectivity (IPv6 ->

IPv6/v4 proxy -> IPv4)

This will financial impact your

business and how productive

your employees are

CGN is NOT a WIN, it is

expensive and kicks the can

down the road

IPv6 Subnetting Best Practices

Stick to increments of 4!

You need to Get Serious about

IPv6

How do I get started?

IPv6 Technical Resources

IPv6 Deployment Resources

“At the current rate of acceleration, we can

expect the majority of the Internet to be

IPv6-enabled around the end of 2015.”

- Own DeLong, ARIN Advisory Council

“No longer is IPv6 adoption "just around

the corner." It's here.”

- Erik Nygren, Chief Architect for Akamai

“At MCI, we have made a full commitment to

implement and deploy IPv6 during 2005.”

- Vinton Cerf, frm SVP MCI and current

Chief Internet Evangelist for Google

What steps do I need to take?

Education

You, your staff and your

partners need to

understand IPv6

This means getting

educated on IPv6

How to design, deploy,

operate and maintain a

network running IPv6…

You will also need to

understand impacts of a

dual-stack environment

You will need to have an

education plan and

resources in place for staff

This does not happen

overnight, start now!

Have a plan

Once your staff is

educated it is much easier

to build a plan

A plan that is tailored to

your business needs and

requirements

A plan that accounts for

what your business does

Without a plan you will fail,

especially if you deploy

IPv6 without one

Your plan should include

testing and validation of

both network and apps

You will need a lab – trust

me on this one

Build a core team

You will need people from

every team

Why?

Because while IPv6 at first

glance appears to be a

networking only function…

You will quickly figure out

that the application teams

need to understand it

The database team will

need to know it

The helpdesk will have to

troubleshoot it, etc.

Understand the business impacts

You many have critical line

of business applications

that do not work with IPv6

Or partners in parts of the

world might only have IPv6

as a protocol option

Understand what IPv6

impacts before it is a

surprise

You may have third party

software or solutions that

do not support IPv6

If the majority of your

business is on the Internet

then supporting IPv6 is

critical

Are all your teams ready?

I still don’t believe I will be

using IPv6 anytime soon

If you are FINALLY migrating

off Windows XP

What has taken you so long?!?!?

Windows XP EOS April 8, 2014

This means you are deploying a

newer OS. So you WILL be

dealing with IPv6

IPv6 is the future and the

future is NOW!
