So, look at other options:

* Widen the query space by using multiple IP addresses as 
source.  This,
  of course, has all the problems with NAT gw's that the port solution
  did, except worse.

  This makes using your ISP's "properly designed" resolver even more
  attractive, rather than running a local recurser on your company's
  /28 of public IP space, but has the unintended consequence of making
  those ISP recursers even more valuable targets.

Makes you wish for wide deployment of IPv6, eh.

The only real fix I see is to deploy DNSSEC.

You seem to be saying, above, that IPv6 is also a real fix, presumably
because it allows for the 64-bit host id portion of an IP address to
"fast flux". Or have I misunderstood?

It would be nice for someone to explain how (or if) IPv6 changes this
situation since many networks are already well into the planning stages
for IPv6 deployment within the next two to three years.
