Hi Victor,

Unbound can synthesize part of a domain or the whole domain. It is 
possible to manipulate a domain as needed for block lists, redirection, 
or supplemental data. Each "local-data:" or "local-data-ptr:" statement 
is used for an RR before recursive searching. Any typical RR can be put 
in "local-data" including TXT. For extreme measures, "local-zone:" type 
"static" can be used to mask out an entire domain (only serves 
local-data:). The "auth-zone:" clause with URL only zone file fetching 
might also work, but I have not spent much time working with this new 

Hope that helps,
