Today we have a Q&A with Joost Tholhuijsen. Joost is the owner of Tholhuijsen Consultancy and an active member of the Dutch IPv6-Taskforce.



Please tell us a little about Tholhuijsen Consultancy

Tholhuijsen Consultancy assists medium and large organisations in network
migrations. We help international companies in selecting their WAN vendor
and solution, we lead IP renumbering projects and advise in broader IT
infrastructure issues.


When and how did IPv6 began to be a part of Tholhuijsen Consultancy?

Tholhuijsen Consultancy started to orientate on IPv6 in 1999, and in 2002
met with Vint Cerf on the subject. In 2009 IPv6 was adopted as one of the
main activities of Tholhuijsen Consultancy. For Syntens, an initiative of
the Dutch Minisitry of Economic Affairs we developed and IPv6 Workshop for
decision makers in small and medium Enterprises.


What is the current status of IPv6 at Tholhuijsen Consultancy?

Tholhuijsen Consultancy has its infrastructure running native IPv6 and
tunneled IPv6. To properly test the market situation one of the networks is
even native IPv6 only. And But Tholhuijsen Consultancy does see IPv6 not
only as part of it’s infrastructure, but more as part of its core business.
Training, creating practical awareness, creating information material and
advising and assisting in IPv6 integration are our day to day work. Via
www.ipv6specialisten.nl Tholhuijsen Consultancy strives to make practical
and skilled IPv6 specialists active in the market.


In what way do you expect to see IPv6 growth in the next couple of years for Tholhuijsen Consultancy?

Tholhuijsen Consultancy is a member of the Dutch IPv6 Task Force, which
foundation was commissioned by the Ministry of Economic Affairs in 2005. The
general purpose of the Task Force is to promote the adoption of IPv6. The
Task Force however has limited means to fullfill its role. Internationally
and nationally outside the official IPv6 promotional bodies number of
initiatives arise. Some important web-sites like Google and YouTube see it
as their responsibility to promote IPv6, and have made their sites IPv6
reachable. Others like Ebay’s Marktplaats strive to do so on a short term.
We expect that initiatives like these help in breaking the infamous
chicken-egg situation that some see as the main barrier for IPv6. Awareness
of the coming IPv4 shortage is rising, but even in the top 20 of best
visited web-sites in February 2010 it was still not at 100 per cent.


Are there any things you would like to say about IPv6 in general?

ICT infrastructures are run by people with broad responsibilities.
Stakeholders are users, management and last but not least controllers.
Implementing IPv6 is not trivial for all of these parties. The speed in
which IPv6 is adopted for this reason does not follow the aspirations of
IETF, IANA, ISOC etc. at the pace of these parties. Given that fact that
IPv6 is necessary, mature and promising, the point of no-return for IPv6 has
been passed some time ago, and organisations ignoring IPv6 might ignore
their role in the mid-term future.



Thank you for your time and your answers Joost and we hope to hear more of your work in the future.
