This might be correct for the US, but definitely not here in Norway:
C:\>nslookup pool.ntp.org
Server: DD-WRT
Address: 192.168.1.1
Non-authoritative answer:
Name: pool.ntp.org
Addresses: 63.211.239.58
128.10.254.6
173.44.32.10

*** DD-WRT can't find 173.44.32.10: Non-existent domain
My WRT54GL WiFi router runs DD-WRT, it is using my local Telefiber DNS
server:
C:\>nslookup pool.ntp.org 94.139.66.250
Server: ns1.telefiber.no
Address: 94.139.66.250
Non-authoritative answer:
Name: pool.ntp.org
Addresses: 128.10.254.6
173.44.32.10
63.211.239.58
I.e. I get the same three servers if I query that server directly.
None of them seems to be anywhere near .no, I get ping times from 130 to
170 ms.
