Dear Ted,

The draft
describes a Special-Use domain but it does not overcome the
need for a domain. There are no valid justifications not to
allow .home as a Special-Use domain. Homenet protocols
require a domain to publish DNS-SD resources to avoid
multicast normally blocked by typical router bridges.

To avoid multicast, DNS-SD resources must not be published
below the Special-Use domain .local. Unfortunately, there
are no Special-Use local non-multicast defined domains where
access can be safely constrained. The alternative use of an
Internet domain necessitates administration of services
exposed to the Internet. Such exposure will necessitate far
greater resources defending against Internet access. Such
increased exposure may also cause private and possibly
critical resources needed locally to become compromised or
made inaccessible.

Why impose the burden of needing to support public domains
on home networks as an aspect of an array of .alt
definitions? A direct singular definition prefaced at the
outset as offering only a private namespace greatly
simplifies and advances homenet development.

This is not advocating for a new TLD.  Rather this is
advocating for the elimination of a Special-Use TLD from DNS
altogether to simplify much needed protection of information.
