Web app to make various DNS queries and get back JSON formatted responses. Handy for doing DNS lookups in multi-language ecosystems without having to re-implement DNS lookups in each application. Just query the app, get back an answer, and parse it.
Works with POST or GET verbs. Always with q as the input.
