If you don't mind some ruby/python, you can use remotebackend for this. # file /etc/powerdns/handler.rb require 'pdns/remotebackend' class EmptyHandler < Pdns::Remotebackend::Handler end Pdns::Remotebackend::PipeConnector(EmptyHandler).run() # eof # file /etc/powerdns/pdns.conf ... launch+=remote remote-connection-string=pipe:command=/etc/powerdns/handler.rb ... # eof sparing any typos you should now have a backend thread that does not respond to any queries other than "does not exist here". you can now set it up to do other stuff as well.
