IPs, running DNS only, and configure the DHCP part of the original
dnsmasq instance to tag DHCP leases given to the children machine(s) and
to pass such tagged clients the alternate IP as the DNS instead of the
The second dnsmasq instance would only catch the youtube domain and use
the original instance as its upstream for anything else, so that any LAN
DNS record configured on the original dnsmasq would automatically be
see by the children machine(s) too.
