So you want the nameservers configured to serve HOMENET to advertise
a well known prefixes (IPv4 and IPv6) into the IGP and as a result
packet routing will direct HOMENET queries to those servers.

That the publically delegated to servers also use those addresses.

I suppose this helps the case of a host using interative resolution
to find the on net homenet servers.
