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::::::: WLAN
fdaa::::::: vbox
fdaa::::::: vdr
fec0:0:0:::1 WLAN
fec0:0:0:::2 WLAN
fec0:0:0::::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
...'.
