       - If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
       - If you are building a RECURSIVE (caching) DNS server, you need to enable
       - If your recursive DNS server has a public IP address, you MUST enable access
         control to limit queries to your legitimate users. Failing to do so will
         cause your server to become part of large scale DNS amplification
         attacks. Implementing BCP38 within your network would greatly
         reduce such attack surface
