Hi John,

unless you want too much work, I would suggest using separate domain for
management names. If you are not afraid management network would be
accessible to all users, just use --server=/mgmt.example.net/ and
--server= for normal names (or just read /etc/resolv.conf for
them). If names are not in separate domain, I doubt there is good
solution. using --server/host-mgmt-1.XY/ may work, but I think
you should ask administrators to create easier system in such case :)

I think I have understood it right, your dnsmasq is just dns proxy for
both networks and does not serve any DHCP or DNS to those networks, right?
