For RANGI transition mechanisms, RANGI hosts will initiate communications with non-RANGI hosts in normal IPv6 fashion (e.g., use one of its locators for establishing communications), just as dual-stack hosts use IPv4 to initiate communications with IPv4 hosts, while non-RANGI hosts will initiate communications with RANGI hosts via RANGI transit proxy, since non-RANGI hosts take the host identifiers of RANGI hosts as normal IPv6 addresses.

Yes.
