Re: AT&T / Verizon DNS Flush?

[Laszlo Hanyecz <laszlo () heliacal net>]

The generally accepted and scalable way to accomplish this is to advertise your freshness preferences using the SOA 
record of your domain.  It would be pretty tricky to make this work with a swivel chair type system for every domain 
and host on the internet.  You would have to contact every user and ask them to invalidate the caches, after asking 
their recursing server operator to do the same.
