Subject: IAB-response: Regarding delegation of sub-country-codes in ENUM

Real requests (and therefore delegations from e164.arpa) can only be on E.164 country codes. i.e. +1, +7 etc.

This will not stop people from requesting +74, +1208 etc.

A request for +1208 (as one example) should be filed as +1208 on
http://www.ripe.net/enum/request-archives/, which will say ‘reject’, as it is not a country code.

If the administrator for +1 (North American Numbering Plan) wishes to delegate +1208 from RIPE NCC as administrator, then first +1 delegation has to be approved. Whether that is to be delegated to RIPE NCC or some other entity is up to the administrator of +1.

So, RIPE NCC can, if they are duly delegated, host the DNS zone for 1.e164.arpa, but whether RIPE NCC want to take on that job (or not) is a decision RIPE NCC has to make, in consultation with the NANP administration.

[The operational arrangement between the IAB and RIPE NCC regarding the administration of the e164.arpa domain does not preclude the RIPE NCC entering into arrangements to administer delegated zones of this domain, as long as all the documented procedures regarding the delegation are duly followed.]

The formal e164.arpa zone delegation, from an IAB perspective, is from e164.arpa to 1.e164.arpa.
