-B, --bogus-nxdomain=<ipaddr>[/prefix]

Transform replies which contain the specified address or subnet into "No such domain" replies. IPv4 and IPv6 are supported. This is intended to counteract a devious move made by Verisign in September 2003 when they started returning the address of an advertising web page in response to queries for unregistered names, instead of the correct NXDOMAIN response. This option tells dnsmasq to fake the correct response when it sees this behaviour. As at Sept 2003 the IP address being returned by Verisign is 64.94.110.11
