Re: ASN to IP Mapping

Users of this report should be aware that there are some subtle deviations from this spec in the published data: - the RIPE NCC uses the non-ISO 3166 2 letter code 'EU' for some allocations. I do not know exactly why;

EU is, of course, an ISO-3166 2 letter code, it just happens to be "Exceptionally Reserved". I would naively have assumed EU was used for entities that span multiple European countries.

- the date field is not quite as described in that file for ARIN entries. Again, I do not know why. - the RIPE NCC does not provide the "opaque-id" in their records
