Nominum IPv6 Deployment Survey

Key
Highlights

Overview

Nominum surveyed
major ISPs

to understand

the state of

IPv6 deplo
yments leading up to the IPv6 Launch. The
goal of the survey was to get a
current
snapshot into the state of IPv6 deployment,
ISPs’
pla
ns for deployment and
their business
reasons

for
moving to IPv6
.

The good news is that

almost every ISP has a plan in place to deploy
IPv6

and by
the end of this year

almost 60
 of networks should support IPv6

(an increase of over 150 since the
start of
the year)
. Major regional differences remain though, with
Europe
an ISP’s facing the greatest risk

of IPv4
address exhaustion prior to IPv6 deployment. A
n encouraging sign

is the fact that 80 of ISPs

plan to deploy
native dual stack as opposed to other s
horter term transition approaches

such as carrier
-
grade NAT
.
Almost all
ISPs
surveyed cited

getting the address space they need to grow their business

as the primary reason for
upgrading to IPv6
but don’t appear to appreciate

the other business benefits I
Pv6 offers
.

Methodology

The
survey
data was collected over a several month period
from

Nominum customers and other industry
participants through online questionnaires as well as in
-
person meetings. The ISPs included in the report
provide
service to

over
110 million
Fixed Broadband
ho
useholds from around the world. Europe, which includes Eastern
Europe, was overrepresented in the survey compared to the percentage of the world’s broadband subscribers,
whereas Asia (excluding Japan) is notably under
-
represe
nted. The exact regional breakdown of respondents was
as follows:



Europe


54



North America


21



Japan


13



Latin America


13

110 individuals from 67 network operators (almost all ISP’s)

responded

to the survey questions. Respondents
typically held t
echnical roles and in many cases
, but not always,

were the

people who owned IPv6 projects
.


There
were some large mobile operators participating, although the bulk of respondents were mid
-
large
-
sized fixed
network operators.

Deployment status and plans

ISP’s appear to be taking the looming threat of IPv4 address exhaustion seriously with
97 percent of
respondents
having

either already implemented
IPv6 or
a plan in place

to do so.
This is reflected in the fact the number of ISP’s
deploying IPv6 is set
to
increase over 150
p
ercent in 2012
alone
to
58 percent

of the total by the
end of 2012.












While it is encouraging to see that ISPs almost all have a plan in place for IPv6 adoption, there are also major
regional differences in deployment timeframe
s. The graph below shows the cumulative deployment of IPv6 by
region.

The chart
above
reveals major differences in IPv6 deployment timing:




Every Japanese ISP surveyed has deployed IPv6



Only 25 of North American

respondents have deployed IPv6

but

100 plan to by year
-
end



Just 48 of European respondents plan to deploy IPv6 by year
-
end



Only 20 of Latin American ISPs plan to deploy IPv6 by year
-
end

North America appears to have the greatest focus on IPv6 in 2012 (
Note:
ISP’s
responded
from the Unit
ed States
and Mexico but no Canadian ISP’s).
European ISPs appear to have the greatest risk of not making the transition in
time since under current policies the Regional Internet Registry for Europe (RIPE NCC) is projected to run out of
IPv4 addresses la
ter this year.

Latin American ISP’s has more unallocated IPv4 addresses than some regions, but
are also the furthest behind in
deployment.

Transition Mechanisms

The survey also revealed encouraging results regarding the transition mechanisms planned for I
Pv6.

80 percent of ISPs surveyed say they plan to use a native dual
-
stack transition mechanism for their roll outs as
opposed to carrier
-
grade NAT or other alternatives. Dual
-
stack technology
avoids some of th significant
deployment issues with

carrier
-
g
rade NAT which can
slow

the user experience and is more likely to break certain
applications
.


When asked about the
major obstacles
seen

rolling o
ut IPv6 based Internet services it’s clear that consumer
premise equipment is the biggest concern. The top 3

obstacles listed in the survey were:

1

Upgrading subscriber equipment is costly



(56 percent)

2

Subscriber CPE devices don't fully support IPv6

-

(44 percent)

3

Costly to upgrade service provider network to support IPv6



(22 percent)

Business Reasons for Tran
sition

When asked about
the
major business driver
s
for upgrading to IPv6 the
re was a clear winner: Accommodating
subscriber growth. ISPs need more addresses to support the continued growth in subscribers and devices. Beyond
growth, ISPs cite the need to
launch new services such as IPTV, compliance requirements for Gov’t customers,
4


corporate mandate for our business customers and demonstrating technology leadership as additional reasons

for
the transition
.


It’s not surprising that

accommodating new subsc
riber growth was the number one business reason given for
making the change to IPv6. However, most ISPs are not looking beyond software support and interoperability
testing to uncover key business benefits associated with IPv6, such as:



N
etwork efficienc
y

o

IPv6 supports much larger packet size, which makes downloading videos and accessing cloud
applications faster and less expensive.



Business Agility



o

Removing the need to NAT traffic and conserve IP addresses provides a range of options for
network addre
ssing previously unavailable.

o

Selling IPv6 service to

large enterprises (especially ones w
ho have made acquisitions) can help
eliminate the
multiple “islands” of identical private IP addresses connected together by
expensive Network Address Translators (NA
T’s)
.




Competitive Differentiation

o

IPv6 accommodates dramatic growth in IP
-
enabled devices, i.
e. the Connected Home, M2M, etc
and provides a more extensible platform for deploying managed services.


o

IPv6 makes “connection
-
intensive” content such as Faceboo
k or Google Maps faster and enables
new applications such as peer to peer gaming.

o

IPv6 addresses contain much more information than IPv4 addresses including the device
manufacturer and Mac address, a unique identifier for each device on the network. This

will make
it easier for ISPs to offer their subscribers optional network
-
based apps like parental controls
and
security
that allow families to choose what content their kids are allowed to view from
each

device

in the household
.

Summary

The
survey highli
ghts that major ISP’s are taking the deploymen
t of IPv6 very seriously and that

significant
progress is being made

deploying IPv6
. By the end of 2012 almost 60 of ISP’s will have deployed IPv6, an
increase of over 150 since the start of the year. Serio
us regional differences exist, however, with Europe and
Latin America facing the greatest risk of not completing the transition in time. Most ISP’s have seen that dual
-
stack is the best long
-
term option for deployment and are investing the additional reso
urces
in
this transition
approach
.
Finally,
ISP’s are almost singularly focused on using IPv6 to exp
and their address pool

and may
be
missing an opportunity

to leverage

one of the largest technical transitions in the Internet’s history

to create
business
value
.
