Full IPv4 utilization and increasing use of IPv6 is completely
orthonginal to DNS label exaustion. Some have argued that all
the "good" names are taken; e.g. the DNS is exausted. This was
first proposed in 1996 (to my memory) yet more than a decade later,
we see that the domain name system is robust and growing.
With the inherent hierarchical structure of the DNS lable, the
mathmatical upper bound is pretty high and we are no where near
DNS name exaustion. If you have actual data indicating otherwise,
I'd love to see the studies.

DNS names do not -HAVE- to have human understandable components.
In many cases, this is highly desired -BUT- is not required for
use. And yes, numeric literals have been used in the past.
Use of the IP address instead of the name is one of the failures
of application design. The IP address indicates WHERE a node is
in the Internet topology, not the identity of the node. The
Name is the indicator of the node IDENTITY. the DNS maps names to
addresses and makes no assurance as to the human friendliness of the
name or the reachability of the address. Your assertion that the
"DNS system can be thowed away" is vacuously true. If you find it
non-useful, there is no requirement for you to use it. Many people
use the DNS to get a lable, memorable or not, and then use other
tools to map that lable into something meaningful... e.g. SEARCH.
It does not invalidate the use of the DNS in any way.

I think I prefer SEARCH to be outside the DNS (having actually
built a varient of the DNS which supported regular expression
expansion of the "?" and "*" characters...)
Your milage will vary.
