Richard,

three short questions:

- subscribers must have [ ] Austrian citizenship [ ] Austrian residency [X] neither one, ie. it's gobally open

There is a vague restriction in the numbering ordinance about usage of those numbers - the "usage focus of the number must lie within Austria" - wherever the "usage focus" of an internet based service consisting of DNS, gateways, access, provisioning etc. might be ...

- registrars must [ ] have a certain license fo Telco operations [ ] be an Austrian company [ ] have at least an Austrian subsidiary From what I understand this is basically dealt with by the answer to the question who is eligible to become an enum.at registrar, correct?

neither one - the domain itself is open to any enum.at registrar. However - to have the corresponding number assigned (which in turn requires to domain to be registered first) you need to have a contract with a licensed Austrian communication service provider (which is not limited to austrian companies!). Practically, i expect most registrars to be the CSP as well, so that you have a contract with just one party. The SP registers your domain, gets the number allocated, and assigns it to you.

- To what extend NP is implemented?

NP is formally done by changing data in the ENUM registry. No re-routing is necessary in the PSTN, since every operator is allowed to terminate any traffic to this number range on a gateway of his choice. cheers Alex Mayrhofer enum.at _______________________________________________ enum mailing list enum@ietf.org https://www1.ietf.org/mailman/listinfo/enum
