as an alternative to '.local'
prior to the related RFC6762 publishing, ".local" was being recommended (by Microsoft, among others) to be used for 'local LAN DNS' kinds of things. I've been using it for ~2 decades. [and I don't care much about mDNS].
Post RFC6762 it's officially reserved for mDNS. Wheee.
NOW we have others, in particular '.home' '.corp' and '.mail'.
Will there be an RFC or similar document to CODIFY and STANDARDIZE these so that we don't get a "whoops, SURPRISE!" later on???
