Hmm, this is what I see from one location. I am testing from two different
networks and have problems on both (one of which I don't run and is
different ASN and backbone)

alpha.usmc.mil  internet address = 192.156.71.40
bravo.usmc.mil  internet address = 192.156.73.40
delta.usmc.mil  internet address = 192.156.13.40
charlie.usmc.mil        internet address = 192.156.5.40
usmcdns1.usmc.mil       internet address = 192.156.78.130

> nslookup -type=A usmc.mil 192.156.13.40
Server:  delta.usmc.mil
Address:  192.156.13.40

*** delta.usmc.mil can't find usmc.mil: Query refused
