Hi,
something like this should work:

1) bind the ip of laptops and android phones to their wifi MAC address
    so that they get handed out always the same ip and your
     internal unbound as dns server

2) set all boxes with wired connections to static ip addresses

3) add:    include: "/var/lib/unbound/local-data.conf"  to your
      unbound.conf file with something like (use your ip):

local-data: "cookie A 192.168.XXX.YYY"
local-data: "cookie.sesame.street A 192.168.XXX.YYY"

4) restart unbound

Ciao,
Tito
