Blacklisting IPs (of DNS records) via additional dnsmasq config

There are two comands, which could allow for filtering DNS records resp. the returned IP address:
bogus-nxdomain=<ipaddr>
and
ignore-address=<ipaddr>
with the first providing some kind of indication, that the IP was blocked, and the latter causing a silent reject. I think these options may provide an additional flavour of filtering, useful as at least adblock lists can contain blocked IPs, not only domain names.

A feedback for the user is out of scopre for this feature, as dnsmasq is not providing a mapping, just ignoring the reply from the upstream server, not forwarding the client (similar to the context given in this feature request).

Edit:

-V, --alias=[<old-ip>]|[<start-ip>-<end-ip>],<new-ip>[,<mask>]
Modify IPv4 addresses returned from upstream nameservers; old-ip is replaced by new-ip. If the optional mask is given then any address which matches the masked old-ip will be re-written. So, for instance --alias=1.2.3.0,6.7.8.0,255.255.255.0 will map 1.2.3.56 to 6.7.8.56 and 1.2.3.67 to 6.7.8.67. This is what Cisco PIX routers call "DNS doctoring". If the old IP is given as range, then only addresses in the range, rather than a whole subnet, are re-written. So --alias=192.168.0.10-192.168.0.40,10.0.0.0,255.255.255.0 maps 192.168.0.10->192.168.0.40 to 10.0.0.10->10.0.0.40

seems to be the correct handle for the feature. As new IP should be pointing to localhost, to handle the request on the pihole engine.
