Consideration: Since every /64 in IPv6 carries it's own distinct geolocation info, there must be somewhere a database of -quick average- 2^64 = 18446744073709551616 records.
I'm currently trying to figure out where that database is located. It may be inside DNS, or it may be elsewhere, I do not know. There is a DNS "LOC" record, but that doesn't seem to be used anymore. It seems to be something else. But what, and where? -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list ISC funds the development of this software with paid support subscriptions.
