proposal
add a Carrier ENUM subtree (branch) under e164.arpa
Branch location is a per-CC decision
Provide mechanism to locate country CE subtree
Carriers may populate that subtree
What a „carrier“ is is a national matter
This suggest a branch under .e164.arpa
But also enable different scenarios like:
.carrier.e164.arpa or
Carrier...e164.arpa
Regarding resolution and management, Carrier and User ENUM tree should be „ships in the night“
