A customer asked us to put on a DNS Resolver for its network.

What he requests is: A list of allowed domains (white list) that the dns resolver can answer (anche cache) Any other domains outside the whitelist must return a invalid dns record.

This is to allow access from his network to only few domains and block any other domains.

What software can i use? I have see powerdns recursor can be used with lua scripts but before try this way i ask if there is something already cooked...

Thank you Francesco


You can use BIND or linux beacuse is free and open source or you can use DNS server on Widnwos server 2003/2008.

You must configure manual zone which you want to serve clients. You must to delete root hints servers from config.

  • Thank you, but: suppose i want to use bind, how can i keep zone updated?. For example, I want to enable sites like gmail.com, how can i set up a manual zone for it and keep it updated? – CeccoMe Oct 11 '12 at 11:51
  • Maybe you can use stub zone ? – tasmanian_devil Oct 11 '12 at 18:48
