Only to get to sites blocked as "security risk" when researching DNSSEC

in 1996 or so, an IOCCC entry (didn't win but got honourable mention)

For PowerDNS:

Hello,
Unbound is known to use banding of about 400 msec, and bind 9 also used
banding(~128 msec) until 9.8 when they removed it.
More information here:

Now they use Smooth RTT.

Hi,
are there any studies or anecdotal evidence about how recursive
resolvers select a query destination from a set of authoritative servers
with known RTTs, and how often they re-probe the slower ones?
Specifically, how many queries in what period of time would it take
until a BIND or Unbound ha
http://code.kryo.se/iodine/ allows you to set up a full IP(v4) VPN over DNS.
Obviously a VPN type setup with IP packet headers and TCP retransmits etc
doesn't help performance compared to a program implementing its own data
channel over DNS, but it does mean it works with unmodified software.
