How can i control how much Authority RRs a DNS answer returns ?
- by Benoît
Hello,
i quite don't understand Authority RRs.
Using dig to resolve some random A records, my caching DNS server sometimes also return Authority RRs and sometimes not. The number and the type of the returned Authority RRs also vary a lot.
What does control whether Authority RRs are returned or not on a standard client query ? Is it a client or server setting ?
What does control how many Authoriy RRs are returned ?
What does control of the type of the Authority RRs records returned ? Sometimes it's multiple NS, sometimes it's a SOA. It's also often comes with Additional RRs of type A about the Authority RRs NS returned.
I'm really looking for a RFC or kind of describing this.
Thanks.
