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 *


    ;; Got SERVFAIL reply from 68.237.161.12, trying next server
    ;; Got SERVFAIL reply from 71.243.0.12, trying next server

    ** server can't find 72.2.123.204.in-addr.arpa: SERVFAIL
    $ *ping -c 4 204.123.2.72 *
    PING 204.123.2.72 (204.123.2.72): 56 data bytes
    64 bytes from 204.123.2.72: icmp_seq=0 ttl=53 time=76.880 ms

    64 bytes from 204.123.2.72: icmp_seq=3 ttl=53 time=69.613 ms

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.
