Editing Djbdns (section)

==Design==
In djbdns, different features and services are split off into separate programs. For example, zone transfers, zone file parsing, [[DNS cache|caching]], and [[recursion|recursive]] resolving are implemented as separate programs.  The result of these design decisions is a reduction in code size and complexity of the [[daemon (computing)|daemon]] program that provides the core function of answering lookup requests.  Bernstein asserts that this is true to the spirit of the [[Unix]] operating system, and makes security verification much simpler.{{citation needed|reason=Where did he assert this?|date=May 2016}}
