Annex C (normative):
Naming convention
This normative annex defines a naming convention which will make it possible for DNS servers to translate logical names for GSNs and RAs to physical IP addresses. The use of logical names is optional, but if the option is used, it shall comply with the naming convention described in this annex. The fully qualified domain names used throughout this annex shall follow the general encoding rules specified in clause 19.4.2.1.
