“Oh, you know UNIX? Good, we need you to run our DNS.”

If you’re like the majority of our training participants, your career
in DNS* started in a similar fashion. Your knowledge of the protocol,
the resilience of your DNS infrastructure, whether or not you like to
use valid shortcuts in config files and so on are often very dependent
upon which team you found yourself in when you first landed in the DNS
world. For the more fortunate among us, the team was “RFC aware”, had
a book or two on DNS and existing, working configurations from which
to learn. At the other end of the spectrum, some of us have landed
where the mention of DNS just elicited a finger pointing to an old
dusty machine under an unoccupied desk.

Amazingly, no matter the landing point, folks usually don’t find their
way to a training until they have a few years of DNS experience. This
speaks volumes about the protocol design and implementations. It also
says a lot about the adaptability and tenacity of DNS admins. The
critical nature of our “DNS inheritance” becomes very clear, possibly
more quickly than we’d like. One does what needs to be done to
resolve and prevent issues in a timely manner. Unfortunately, these
qualities often produce a “why invest training dollars when you do
such a fine job with DNS” hurdle for admins when trying to justify
taking a formal course. (Please forward this blog for possible help
with that…)

Whatever the length and depth of your DNS experience, an ISC training
course is an excellent opportunity to expand your understanding. We
discuss the original protocol design goals and how implementation has
played out in the real world. Our intensive hands-on labs offer you a
fresh environment where you build, configure, implement and
troubleshoot. From experienced DNS admins we often hear comments such
as “so that is how that works”, “wish I had known that trick years
ago” and “this really filled in the gaps for me.” For those newer to
DNS, you will leave with solid footing and plenty of tips and practice
to make sure your DNS behaves as it should.

We offer public trainings around the world with our training partner,
Men & Mice. For our most recent schedule of public trainings, please

We also offer private, on-site trainings. Please inquire with
training@isc.org if interested.

But wait, there’s more! ISC training participants receive a
complimentary attempt at one of our Certification Exams. For more
information on our certification program, please visit:

* Please re-read this blog substituting “DHCP” everywhere you see
“DNS”. We promise it works, it’s true and it’ll be fun!

If you are an executive or manager whose business model relies on
DNS, perhaps you’ve said similar words. Often, “DNS Just Works” and
you are fortunate enough to maybe not even know who or what team
handles this critical aspect of your business. If so, we invite you
to consider how much you have invested in infrastructure not
specifically related to DNS. Now, think about your return on that
investment should DNS no longer function or become even occasionally
unreliable. Does your recurring investment in DNS match its
importance to your business? If not, ISC training is a good place to
begin bridging that gap.
