Hi Wouter,
thank you for the answer, but ...

since my list of blocked domain is hundred of thousands i need to change 
the "default TTL" lower than 3600 for all redirect data
the purpose is for efficiency, if inserting TTL on every single line 
local-data it will consumes huge RAM in the system.

somehow if there is a blocked domain and i remove the line from the list 
and then restart unbound, the domain still blocked for 1 hour
i need to modify the default TTL to ... let say 300 or 900 secods
should I edit the source code, where, which part?
