IPv6 networking: Bad news for small biz
### You may not get fired for buying Cisco, but you can go bust
From the comments the author opines (among other things):
The article exists for one reason: to let the high priests of the internet
know "oh, BTW, that NPT66 thing that? It's in products and in use in SME shops
all over the damned place already." In other words: the utter failure of the
priesthood to engage care for the issues faced by SME outfits resulted in them
(shockingly!) going out and choosing the cheap and simple alternative that
actually already existed! Note the two key words: "cheap" and "simple."
That's us he's talking about. It seemed only fair to share that perspective,
since I don't see any other mention of the article here. Needless to say, I
really can't speak in polite terms of some of the shortsightedness
But of course, I'm always delighted to hear your opinions. Is renumbering
*really* that big of a deal? I suppose multihoming is the bigger, more
serious concern - that's the one we see no viable solution but NAT for, given
small site constraints and aggregation. And yet, here we are, on our way to
flipping the big switch, and nobody seems to be in much of a panic. I do not
operate on sites large enough, or disaster-resistant enough, to know one way
or the other how big of an issue this really is. My gut feeling is that this
article is not the whole story and that the author has worked up a good
whinge. But I do think the belligerent attitude in this article says we won't
be long finding out just how far a NAT-free existence will get us. Especially
true given how much blame we get for "Not thinking it through properly" or,
worse, directly compared with OSI protocols with all those fancy network path
discovery features that we felt we didn't need, application-layer DNS kludges
for failover, etc, that would have remediated these problems if the naysayers
are to be believed. No doubt there's work to be done. I see already the
progress made in v6ops of IPv6 multihoming without NAT. Cool. And, of
course, there's HomeNet for putting the title of this article into question.
Of course, The Register does have a reputation of being an IT tabloid, but ...
Renumbering in small organizations _is_ a big deal, especially when they don't
have in-house skills to manage systems.
They may not even have the skills to determine that something deployed in their
network has failed renumbering, or is left behind due to static configuration.
I was at "Cisco Live" a week or so ago, and the Cisco advisor stated that
people should use PA Global addressing and not even look at ULA (even for
With approaches like that, renumbering will be a significant pain, or people
will just not change ISP.
What we need is simple, template guidance for SMEs that can be deployed to
reduce the risk of future costs in IPv6 deployment, and minimizes the cost of
operating and troubleshooting networks in the mean time.
