Yeah, but this isn't necessarily the fault of the nameserver -- it could
be the result of an ignorant or overly aggressive firewall administrator,
Of course, there are certain authors who would argue that the requirement
to support TCP is inherently broken, but I don't think we want to go down
At the very least, I think we can argue that this should be considered a
serious warning, but I do not believe that it should necessarily be
considered a drop-dead forget-testing-anything-else failure.

So long as two of them have different IP addresses, you should be okay.
If the same machine has different names and more than one name for that
machine is listed as an NS for a given zone, then it shouldn't necessarily
be considered a hard error.
