At least the E space is largely usable last I checked (eg: IOS-XR, JunOS). You can even measure traceroutes that have the class-e space in them from some cloud providers if your network and the intermediaries don’t do u-rpf as well. Most OS’es (MacOS, Linux, various *BSD) also permit this as well. My understanding is that the RedmondOS may not handle this, but if you need to number your infrastructure these addresses may work well. - Jared
