Presumably, they didn't establish one because 1) that's outside of the scope of the BRs and 2) that's someone else's job, not theirs. Regardless, as I pointed out in a comment [0] a few days ago on another thread, there are several such "special-use" domain names, although none specifically "for development purposes". You won't be able to get a certificate signed by a PKIX CA for them, though; you'll just have to make your own. -- [0]: https://news.ycombinator.com/item?id=25531515 https://news.ycombinator.com/item?id=25531515
