Take the 2-minute tour ×  I'm setting up a simple DNS server
(BIND/Named), which is running locally on a OSX Laptop.  Its
purpose is to resolve all requests for "*.laptop.example.com" to
"" - which is the manually assigned IP address (not DHCP) of a
virtual network interface.  I'm using a virtual network
interface (provided by Parallels) to ensure the IP address
always remains the same (eth0 will change its IP address when
connected to different networks), and to also ensure it is
always available (eth0 is disabled/unavailable when a network
cable isn't plugged in).  I have been using the following setup:
options {     forwarders {;   forward only;   However this
requires the configuration to be updated each time the laptop
changes network (as most networks have a different DNS address
to use).  I would like to drop this requirement so that if
BIND/Named does not recognise the domain name (i.e. it isn't a
sub domain of "laptop.example.com"), then it returns an error so
the laptop can try the second DNS addre
