3. www.ietf.org AAAA RR はどこに
階層との関係
'www.ietf.org' can be defined in four different places. It could be in the 'root' zone itself, fully written out: www.ietf.org IN AAAA 3600 2400:cb00:2048:1::6814:55 Or it could be in the org zone, where it might look like this: $origin ORG www.ietf IN AAAA 3600 2400:cb00:2048:1::6814:55 Or, (as is actually the case), this name could live in the 'ietf.org' zone: $origin ietf.org www IN AAAA 3600 2400:cb00:2048:1::6814:55 And finally, it is even possible that there is a zone called 'www.ietf.org', where the record lives like this: $origin www.ietf.org @ IN AAAA 3600 2400:cb00:2048:1::6814:55
4. 権威サーバーの動作
あるいはzone cutsについて。
When an authoritative server receives a query for 'www.ietf.org', it consults which zones it knows about and answers from the most specific zone it has available.
この説明は現状の一部を記述しているに過ぎない。
