I've never heard that claim before. I've run experiments with DNS
and found surprisingly few limits on how far it can expand. (For
example, in one experiment [more than a decade ago] we ran Bind with
tens of millions of top level domains and then ran query traffic [in
which we mixed a fair amount of absent names to make it more
real-life.])<br>

DNS was designed in the mid 1980's, and the biggest of computers we
had back then are overmatched even by rather small devices of
today. The laptop I'm using to type this makes the Crays I used
(for magnetic confinement fusion simulations) seem rather weak.<br>
<br>
However, there is an intriguing side vector, which is that DNS is
fading as a user-visible technology.<br>
<br>
This does not mean that DNS is going to disappear, rather that it is
being submerged to become an internal internet name/address
technology. IP and MAC addresses used to be far more visible to
users. They became submerged under DNS names. DNS is now following
that path and being submerged under URI based names and
application-local names (such as Facebook names, hashtags, Twitter
handles, etc.) Even URI names that contain long DNS names and index
data are being submerged under shortened names. I anticipate that
attribute-based naming systems will come to dominate in certain
areas (I am sure, however, that if one were to look inside such
systems that DNS names will be there serving as internal machinery.)<br>
<br>
There is at least one of the new top level domain offerings that is
based on the idea that this kind of DNS submergence is happening.
It's (partial) focus is on DNS names used to located technical
resources; the human semantics of the names is not particularly
important because it isn't humans who are uttering those DNS names.
On the other hand, because a flexible human has been supplanted by
embedded firmware, the value of long term persistence of a DNS name
is more important than cute words that such a name might contain.<br>
