Block and redirect domains with dnsmasq

Reading the dnsmasq manpage I found the following:
A, --address=/<domain>/ [domain/] <ipaddr><br /> Specify an IP address to return for any host in the given<br /> domains. Queries in the domains are never forwarded and always<br /> replied to with the specified IP address which may be IPv4 or<br /> IPv6. To give both IPv4 and IPv6 addresses for a domain, use<br /> repeated -A flags. Note that /etc/hosts and DHCP leases over-<br /> ride this for individual names. A common use of this is to redi-<br /> rect the entire doubleclick.net domain to some friendly local<br /> web server to avoid banner ads. The domain specification works<br /> in the same was as for --server, with the additional facility<br /> that /#/ matches any domain. Thus --address=/#/1.2.3.4 will<br /> always return 1.2.3.4 for any query not answered from /etc/hosts<br /> or DHCP and not sent to an upstream nameserver by a more spe-<br /> cific --server directive."

This seemed to be exactly what I wanted. It redirects any server in a given domain to a specified ip address

sample of my /etc/dnsmasq.conf: (where 192.168.1.1 is the local webserver)
address="/ac.rnm.ca/192.168.1.1"<br />address="/accelerator-media.com/192.168.1.1"<br />address="/action.ientry.net/192.168.1.1"<br />address="/actionsplash.com/192.168.1.1"<br />address="/actualdeals.com/192.168.1.1"
