Post #3041184

@sindastra@chaos.social @bekopharm@social.tchncs.de exactly; ".local" and a few special ranges of arpa reverse-dns domains are reserved for special use by RFC6762 and should not be used for anything other than Multicast DNS. The special handling for these domains is described in https://www.rfc-editor.org/rfc/rfc6762#section-22.1 - includes things like that DNS libraries and DNS servers should recognize the domain and refuse to forward/resolve queries for it.
