I'm not sure I'm following all this.
I didn't see that usno.hpl.hp.com exists, see below. There doesn't
appear to be any DNS name associated with the IP address. It does
respond to a ping.
$ *ping -c 4 usno.hpl.hp.com*
ping: cannot resolve usno.hpl.hp.com: Unknown host
$ *nslookup 204.123.2.72 *

I checked the IP address and host name against a number of DNS servers.
It does not respond to a time request on port 37

Getting time on TCP port 37 is /old/. I only do it because that is all
I have until such time as I port something smarter. Note the following
from NIST: "We will continue to support the "TIME" protocol that uses
TCP port 37 for the forseeable future." So not responding on port 37
might not be a false negative, if only NTP is supported.
