with dnsmasq (the stock openwrt dns server) that would be the
"--address" option

-A, --address=/<domain>/[domain/]<ipaddr>
    [...] Thus --address=/#/1.2.3.4 will always return 1.2.3.4 for any
query not answered from /etc/hosts or DHCP and not sent to an upstream
nameserver by a more specific --server directive.

so, try appending the following line to /etc/dnsmasq.conf and restart
the daemon:

address=/#/2.2.2.2/

something like

# echo "address=/#/2.2.2.2/" >> /etc/dnsmasq.conf
# /etc/init.d/dnsmasq restart

why not? :)

cheers!
