A long long time ago in a network far far away, one of our campus NTP servers
was a machine under my desk.  That machine was shut down
around 2002/06/30 22:49 and we didn't re-assign the IP address ever since
*because* it kept getting hit with NTP packets..  Yes, a decade ago.

A few months ago I ran a test of how many things were still using it. In the
first 15 minutes, 234 different IP's tried to NTP to that address, which has
been a black hole for a decade.  After 3 hours, I had almost 2,000 IPs.

Interestingly enough, the *hostname* is still in use (by another machine under
my desk) - and it gets near zero hits.  So it's all hardcoded IP addrs not
hostnames.
