Dear Suzanne,

Names rather than addresses, especially for IPv6, is well
ensconced as a means to establish user friendly network
configuration access. As such, special names greatly aid
network development, such as 'localhost' and '.local'.

Homenet is attempting to instantiate multiple router
configurations that function independent of external
services.  While names like 'localhost' and '.local' have
greatly aided network development, these names are limited
to immediate hosts or multicast. For this new environment, a
name able to establish user friendly configuration access is
needed.  DNSSD WG has proposed and supports '.home' for this
purpose.

Lacking standards body leadership or guidance, equipment
providers tend to use arbitrary names or hard-coded
addresses to bootstrap even single router configurations.
Homenet needs to standardize how to manage the configuration
of multiple routers.

As in the past, use of specialized names offered the least
onerous solution. As '.home' has been adopted in various
products, a special use names registry that includes at
least this name is both prudent and vital at aiding local
multiple router development.

Methods to further instantiate names within this specialized
environment is then better able to proceed and avoid
interfering with existing services. Names included within
this service might be derived from existing protocol hints
and less likely though explicit user interaction. In any
case, configuration must not depend on external services.
