Dear Mike, http://tools.ietf.org/html/rfc6281 offers a fair amount of detail about safely leveraging home networks. Further examination of this scheme shows selective publications of devices in DNS and expects other services to be indirectly shared by these devices. It makes extensive use of ULAs that offer a stable basis for publishing addresses in DNS. http://tools.ietf.org/html/rfc6890 and homenet arch also references use of ULAs. http://tools.ietf.org/html/draft-ietf-homenet-arch-17#section-3.6.6 3.6.6. ULAs as a hint of connection origin The basic security related premise employed by mDNS can be confirmed by use of ULAs. It is also conceivable anti-distribution protection schemes can be satisfied when ULAs have a common prefix. There are also many home routers already able to combine GUA and ULAs. Add L2TP and it seems we are done. Regards, Douglas Otis
