DNS Checker

We have just released a new utility in the Apple app store. It tests recursive DNS servers for conformance against current DNS protocol specifications, especially with regard to EDNS(0) as specified in RFC 6891.

Like our other utility on the app store, Dig, this is a free download, and we do not provide formal support for it. Ray Bellis, ISC’s DNS Researcher, is the author.
