This inspired me for a little experiment (Norway is still small enough).

I dug out all A-records from the no domain (Norway). All this hosts, a
total of 5912 addresses, was sent an ntp packet. This included a bunch
of routers, PC's, mac's, terminal-servers and other random equipment
which I would not expect to respond to ntp packets anyway. I ran the
test just once, so hosts beeing down or othervise unable to respond at
the moment they where probed could skew the numbers slightly. Things
with more than one ip-address was tested mulitiple times which also
tend to introduce inaccuracies.

Here are the numbers.

Hosts running ntp:      466
Hosts not running ntp: 5446
Total number of hosts: 5912

This indicates that about 8% of all registered ``things'' with an
ip-address in norway was running ntp and responding to ntp requests.
