It may be more of a problem with DNS Crawler. It works fine with dig and
my home brew equivalent of DNS Crawler.
There does seem to be something of a problem with UDP and the router just
beyond Comcast's router at 68.86.100.86. Need to switch traceroute from
its default UDP to ICMP to reach CAWUNITED.COM.
This is a good example of why you don't want both name servers for a
domain on the same network.
