var dnsMessage = await _dnsClient.QueryAsync(host, DnsQueryType.ANY, cancellationToken: CancellationToken.None);

This throws exceptions on Cloudflare's DOH service. I have to search for specific types (A, AAAA, etc.) and it works fine.

2. Attempting to send multiple types in one request doesn't seem to work. I modified this a bit and sent a Question[] for A,AAAA,CNAME and this didn't work. Would be nice if there was a way to do this more naturally.

Looking to set this up to gracefully check between IPV4/IPV6 as needed and having some issues.
