Hi, Patrik,

I have two questions regarding your ENUM draft.

In "draft-ietf-enum-e164-dns-00.txt", you use the replacement field of
the NAPTR RR to store the the URLs for the answer of an E.164 query,
such as a SIP URL "sip:paf@swip.net". When I looked through the NAPTR RR
documents, both RFC2168 and "draft-ietf-urn-naptr-rr-03.txt" say that
the replacement field MUST be a fully qualified domain name. Maybe I am
missing something. Could you explain the difference here?

The second question is regarding the service field "N2R". According to
RFC2168, "N2R" is a service that maps an URN to an instance of resource.
Since an ENUM query returns a set of URLs, will that be "N2L" instead?

Thanks in advance for your clarification.

--Hong
