The vbox related stuff is described above. The whole file is:

Web-Shell>  cat /var/hosts
127.0.0.1 localhost
192.168.25.1 WLAN
192.168.25.2 vbox
192.168.25.6 vdr
192.168.25.10 netbook
192.168.25.12 netbook-openvpn
192.168.25.18 defy

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
fdaa:aaaa:aaaa:aaaa:eeee:eeee:eeee:eeee WLAN
fdaa:aaaa:aaaa:aaaa:bbbb:bbbb:bbbb:bbbb vbox
fdaa:aaaa:aaaa:aaaa:dddd:dddd:dddd:dddd vdr
fec0:0:0:ffff::1 WLAN
fec0:0:0:ffff::2 WLAN
fec0:0:0:ffff::ffff:2 vbox

WLAN is the router on which dnsmasq is running. I see such a message for vbox, but I don't
see a message for WLAN. The address for WLAN are set dircetly by 'ip addr add ...'.
