[Dnsmasq-discuss] Why doesn't this machine have a name?

I run a small home network with dnsmasq running on one of the machines
to provide DNS and DHCP services. It all works fine but I've just
noticed that when I connect a laptop running xubuntu 11.10 to the system
it doesn't register its name with the dsnsmasq server.
Other machines seem to provide names without a problem (also running
xubuntu 11.10 or 11.04).
The laptop is working OK in every other respect, it can see the internet
and DNS works fine.
The server is running dnsmasq version 2.52 and runs ubuntu 10.04 LTS.
It's pretty much a default setup, there are some static addresses set up
192.168.1.1 vigor 2820n
192.168.1.2 dps dps.zbmc.eu
192.168.1.3 hp7310 HPEDDBB7 HP000D9D068F7D
192.168.1.4 chris wiki boat info zbmc.eu
192.168.13.254 2wire BT2700HGV gateway.2wire.net
... and some simple additions to /etc/dnsmasq.conf:-
# Custom additions
If I do "arp-scan -l" from my desktop machine (chris) I see:-
192.168.1.1 00:50:7f:8b:35:40 DrayTek Corp.
192.168.1.2 00:01:6c:6c:c7:9b FOXCONN
192.168.1.6 00:04:4b:07:13:30 NVIDIA
192.168.1.83 00:50:8d:93:fd:09 ABIT COMPUTER CORPORATION
192.168.1.88 00:90:a9:70:06:ff WESTERN DIGITAL
192.168.1.99 00:23:8b:de:b6:d9 Quanta Computer Inc.
192.168.1.122 78:ac:c0:63:90:d4 Hewlett Packard
192.168.1.84 70:f1:a1:2d:da:86 Liteon Technology Corporation
... and then:-
root at chris:~# host 192.168.1.83
18.104.22.168.in-addr.arpa domain name pointer test.zbmc.eu.
root at chris:~# host 192.168.1.99
Host 22.214.171.124.in-addr.arpa. not found: 3(NXDOMAIN)
root at chris:~# host 192.168.1.84
126.96.36.199.in-addr.arpa domain name pointer laptop.zbmc.eu.
root at chris:~#
So why doesn't 192.168.1.99 have a name? Both test.zbmc.eu and
laptop.zbmc.eu are running versions of xubuntu and they work perfectly
OK. The only *very* slight difference with 192.168.1.99 is that its
name is acer-aspire, would that '-' have any effect?
