Deployment of important new DNS features such as DNSSEC relies on end users having access to DNS resolvers which behave correctly per the specifications. This app, from ISC Research, tests recursive DNS servers for conformance against current DNS protocol specifications, especially with regard to EDNS(0) as specified in RFC 6891. The app can automatically detect the DNS servers automatically discovered by your iOS device, or you can enter IP addresses to be tested manually. Both IPv4 and IPv6 are supported.
