to pass bits, in the IPv4 world, DNS is -NOT- critical.
no application forbids address literals and every app
will allow address literals to be used. Couple this with
the fact that IPv4 addresses are within the scope of human
comprehension, i.e. I can remember 128.9.160.160
with IPv6, the addresses are long enough to not be human
friendly, e.g. 2001:0478:6: is about as much as I remember
on my own... I must use the DNS or my little yellow sticky note
to complete the address. And there are intimations that some
applications now forbid the use of address literals, even
if bracketed.
Sounds like you both are arguing that the DNS has become
"embedded" and the applications that use IP are unusable
without a working DNS. This assertion, if true, has ramifcations
beyond a simple requirement to have the latency of an extra
lookup against a third party. (Can you say "Death to e2e!...
sure you can :)
