Matt,

This smells like a dns issue of some kind. If a node has a reverse dns
entry it is displayed as:

 host.name (ip.add.re.ss)

But if the node has no reverse DNS entry then netdisco should just
display:

 ip.add.re.ss

So the fact you're getting:

 .99.2.52 (10.99.2.52)

Would suggest that netdisco has done a reverse lookup on 10.99.2.52 and
found it resolves to .99.2.52. What does an nslookup for 10.99.2.52 give
you?

It's probably worth noting that ubuntu enable mdns by default and this
has caused some people issues in the past. It might be worth going
into /etc/nsswitch.conf and removing all references to mdns from the
hosts line, though I can't think how that would cause this specific
problem.
