Exigent Network's Spring News 2011
Welcome to our first newsletter of 2011!
2010 was a very successful year for Exigent with the addition of a number of new clients and significant project deployments
which have allowed us to double our turnover year on year. During the second half of 2010 we completed large projects with
GlaxoSmithKline, Ripplecom Broadband and Fingal County Council while also winning new service contracts with Dun
Laoghaire-Rathdown and Laois County Council.
As of the start of this year, Exigent have also been invited to join Cisco’s Public Sector Partner Program (PSPP) which will
allow us to be more competitive when bidding for public sector opportunities involving Cisco products and technologies.
In terms of new technologies, we would like to bring your attention to the 17GHz frequency which is now license free in
Ireland and our new equipment can provide you with between 30 and 100 Mbps full duplex bandwidth at distances up to 15
kilometers. This new frequency range will offer you a more reliable and cost effective upgrade path for your existing 2.4 GHz
and 5.8 GHz radio links.
We have included below our company news updates, new product highlights and also a FAQ on the IPv4/IPv6 transition that
has been in the technology news lately. We have also continued our newsletter competition so please don’t forget to enter to
be in with a chance to win. Lastly we would like to thank you for taking the time to read our newsletter, we hope the
information provided will be of benefit to you and we would like to wish you all the best of luck in 2011.

A New Look & Home for Exigent Networks:
This week, Exigent Networks announced our new modern, innovative, brand identity and
launched a more intuitive, user friendly website to help us interact
with our current and potential customers more effectively.
In light of our continued growth and expansion plans we have moved to a new office facility
in Eastgate Business Park in Little Island. Our new address is Exigent Networks, Eastgate
House, Little Island, Cork. We would like to issue an open invite to all our clients to join us
at a drinks reception that we will be holding at our new offices in the next number of weeks.
Once the date has been confirmed we will send out the details.
Exigent deploys Major LAN upgrade at GlaxoSmithKline
We recently completed a significant upgrade of the LAN infrastructure for GlaxoSmithKline using the latest Cisco Technology
at its Irish facility in Dungarvan, Co. Waterford. GlaxoSmithKline is one of the largest pharmaceutical companies in the world
and has a significant presence in Dungarvan, where it produces market-leading oral care and over-the-counter medicines.
“Our facilities have a reputation for excellence, delivering quality products to our consumers and we demand the same high
standards from our suppliers,” said Brian Fahy, IT manager, GlaxoSmithKline. “Exigent Networks won and delivered a
number of projects for us using the very latest technology and were a natural choice when it came to carrying out this
upgrade, which they delivered on time and on budget.”

IPv4 Exhausted? A quick FAQ:
1 - Will the Internet stop working?
No. As a matter of fact, it is unlikely that the IPv4 internet will stop any time soon. It will likely co-exist next to the IPv6 internet.
There are some transition mechanisms already setup and while it is not pretty, the two "internets" can currently talk to each
other via proxies and tunnels.
2 - Why do we run out of addresses?
IPv4 allows for about 4 billion addresses. There are about 6 billion people in the world and if you then add up how many
addresses you need - phone, home, work, etc, it’s easy to see that we don’t have enough, let alone for all of the devices that
we don’t think about. The issue is also compounded by the fact that for efficient routing sake, we can't assign all addresses,
so there would never be 100% usage of the IPv4 addresses.
3 - A lot of IPv4 space is still unused. Why don't we use it more effectively?
The problem is not just that we are running out of addresses, even though that is the major issue here. Assigning addresses
more effectively would mean that assignments would become smaller and routing tables would become more complex. In order
to make this work, we would have to essentially "renumber" the internet and then we would still run out of addresses at some
point anyway.
4 - What about legacy space? Does Apple really need a /8?
In the beginning of the Internet, IPv4 address space was handed out very liberally. It was literally just an experiment and some
of the original participants still have large IPv4 assignments which they don't use efficiently. However, even if all of them are
handed back, it would postpone the problem only by 1-2 years and at great expense for the affected companies. Also many of
these organisations have legal contracts giving them rights to the space they have, so it would be both difficult and expensive
for everyone involved. However despite this, some organisations who had large initial allotments, have given some unused
space back already.
5 - What do I need to do today?
Relax, nothing is going to happen fast. The Regional IP Controllers (RIR’s) still have space left, which depending on the region
can last a few months or up to a year. After that, it will get tricky. You may already find it harder to get IP address space.
Eventually, your ISP may ask for some space back as they can't get new addresses from the RIR’s. Over time, IPv4 will get
more expensive than IPv6.
6 - So I can just wait and do nothing?
No. What you should do tomorrow (or maybe some of you are doing it today) is setup a test lab to familiarize yourself with
IPv6. It is easy to get going. Ask your ISP if they support it (or when they will support it), or you can setup a tunnel with a free
tunnel provider like Hurricane Electric [] or Sixxs []. You can then make a plan on how to
deal with it. You will probably find that even if you don't need IPv6 on your network, maybe your business partners will start
using it and you will need to connect to them via IPv6.
7 - Can't I just ignore it?
IP is the primary protocol that establishes the internet, it allows you to connect to customers, suppliers, branch offices etc. In
short: It keeps you in business and communicating. There will come a point when all organisations across the world will expect
IPv6 connectivity, and we will likely have to move along with it then. Think of it like any technology in that it ultimately has to
support the business and organisations. So, no, unfortunately we can’t ignore the issue.
8 - What will change from a security point of view?
Everything and nothing. The most important change is probably the fact that NAT does not exist in an IPv6 network. Endpoint
protection and carefully configured firewalls will become critical as every device will have publicly addressable IP addresses.
Passive asset detection will become more important compared to active scanning and we will need to check our existing
equipment and in particular security equipment, which currently might not be up to the job of protecting us when IPv6 is
