SECURITY AND PERFORMANCE - AN IMPORTANT NOTE adns is not a `full-service resolver': it does no caching of responses at all, and has no defence against bad nameservers or fake packets which appear to come from your real nameservers. It relies on the full-service resolvers listed in resolv.conf to handle these tasks. For secure and reasonable operation you MUST run a full-service nameserver on the same system as your adns applications, or on the same local, fully trusted network. You MUST only list such nameservers in the adns configuration (eg resolv.conf).
