Hi,

I've some trouble with clients in VirtualBox (Linux and Windows 10). The host runs Windows 7. I create dhcp-host entries
for all machines:

dhcp-host=aa:aa:aa:aa:aa:aa,id:00:01:00:01:aa:aa:aa:aa:aa:aa:aa:aa:aa:aa,192.168.255.100,[::0:0:1234:100],host-windows
dhcp-host=bb:bb:bb:bb:bb:bb,192.168.255.110,[::0:0:1234:110],vbox-windows
dhcp-host=cc:cc:cc:cc:cc:cc,192.168.255.120,vbox-linux

If I start a client in VirtualBox, it does hi-jack the dhcp6 name of the host. Both windows machines are using the same
iaid. With 'ipconfig /renew6', I can retrieve the name for ipv6. All machines provide a name by its own. It is the same
name, which is configured for dnsmasq. If I add a duid and a ipv6 address, it doesn't occur. The ipv4 name isn't
affected. The second dhcp-host entry maybe wrong, because it contains an ipv6 address but no duid.

Regards,
Hartmut
