Re: VeriSign's rapid DNS updates in .com/.net

duane wessels' presentation at the last eugene nanog meeting distinguished
between two kinds of traffic received at f-root during his sampling work:
crap: 97.9%; non-crap: 2.1%.  the "crap" category includes requestors who
do not seem to cache the responses they hear, thus rendering the actual TTL
moot.  therefore if there were a drop in TTL for root-zone data, it would
only be a multiplier against 2.1% of f-root's present volume.

but i agree with daniel.  the reason verisign is doing this has got to be
because ultradns does it, and .ORG therefore has marketing hoopla that
.COM/.NET lacks, and parity was needed.  the primary beneficiaries of this
new functionality are spammers and other malfeasants, and the impact of
having it in many TLD's will be to put downward pressure on TTL's.  this
all needs to be looked at very carefully.
