Both are reserved: the ".home" TLD is reserved for the Home Networking Control Protocol in the RFC 7788 that you cited, and ".local" is reserved for some multicast DNS mumbo jumbo in RFC 6762. (There is no good choice, and out of the bad ones, ".local" is OK I guess.) > See RFCs 7788 for .home, and 8244 for .local I didn't know about RFC 8244 (it's from October), but it looks like it only points out the existing problems. I'll go read it. > I think .local was correctly added to 6761, so that domain CAN be used > as your private network's TLD. local doesn't appear in RFC 6761, you might be thinking of localhost? For ".localhost", the RFC more or less states that your users can assume that all addresses resolve to 127.0.0.1, which makes it unsuitable for a network with more than one machine.
