[Dnsmasq-discuss] Why doesn't this machine name get propagated round my LAN?

I have dnsmasq version 2.52 running on an Ubuntu server machine on our
home LAN.

At the bottom of /etc/dnsmasq.conf I have the following:-


The machines backup is a Western Digital NAS that runs Linux, chris is
my desktop machine running xubuntu and ben is my son's games machine
running Windows Vista.

I can refer to 'backup' and 'chris' by name OK:-

    chris at dps:/etc$ host backup
    backup.zbmc.eu has address
    chris at dps:/etc$ host chris
    chris.zbmc.eu has address
    chris at dps:/etc$ 

but not 'ben':-

    chris at dps:/etc$ host ben.zbmc.eu
    Host ben.zbmc.eu not found: 3(NXDOMAIN)

What am I doing wrong?  The MAC address is right:-

    root at chris:~# arp-scan -l
    Interface: eth0, datalink type: EN10MB (Ethernet)
    Starting arp-scan 1.8.1 with 256 hosts (http://www.nta-monitor.com/tools/arp-scan/) 00:50:7f:8b:35:40       DrayTek Corp. 00:01:6c:6c:c7:9b       FOXCONN 00:04:4b:07:13:30       NVIDIA        00:90:a9:70:06:ff       WESTERN DIGITAL       00:04:20:26:55:19       Slim Devices, Inc.       08:00:27:24:d0:9c       CADMUS COMPUTER SYSTEMS       00:01:e3:9d:8b:b5       Siemens AG

The NVIDIA machine is 'ben'.

Is it because 'ben' has a static IP and thus dnsmasq isn't setting its
address? If so how do I get dnsmasq to provide DNS lookup for 'ben'?
