- 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

recursion.

- 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
