A nice form to guide the users
It could be nice to have a beautiful Web form to guide the users in inputing domain names, qtypes, etc.
The REST architecture of the DNS looking glass does not make it easy, since we need a different action depending of what was entered in the form. There are various solutions (formaction attribute in input, but it does not exist in XHTML, or Javascript, which is a problem in itself).
A better solution would be to develop a completely different service, using all the modern bells & whistles, which would call the REST service, get the JSON and display it. A task for someone who knows about Web front-end development.
