Why does the SOA record not contain a collection of name servers? about dnsclient.net

[MichaCo]

you should get 2 NS records back from lookupClient in your example. Each one has 1 MName.

quickly tested it, just in case...

So the type of query I did is QueryType.SOA and it only returns a single record (as expected for the query type). Having said that, I had not tried running a query of type QueryType.NS. That does return two records as expected (and as your updated comment above shows).

Is it reasonable to expect the API surface for a SoaRecord to contain the related NsRecords in the object graph? Personally, I think it's odd that it doesn't.

How does a QueryType.NS query work under the hood? I'm not familiar with your codebase but would appreciate it if you could point me in the right direction so I can better understand it.

Finally, is the best way to get the IP address of an NsRecord to do a subsequent QueryType.A for each NsRecord returned? I was surprised that it's also not available on the NsRecord itself.

The library doesn't do anything special. It returns whatever the DNS Server you are using returns.

There is always only one SOA record and it will return only the primary master NS server.
See https://en.wikipedia.org/wiki/SOA_record

To get all nameservers, you'll query for NS records.

There might be additional answers in the query result which resolve the FQNs of the nameservers.
Public DNS servers usually don't recursively resolve answers though and you'd have to do that yourself.

Got it. Thanks!
