Do not only rely NS Record on parent domain

	nrrs, err := r.resolve(ctx, pname, "NS", depth)
	if err == NXDOMAIN || err == ErrTimeout || err == context.DeadlineExceeded {
	return nil, err
	}

Such as xxxxx.sn.mynetname.net which is used for RouterBoard DDNS function (xxxxx is a random serial number on RouterBoard), the resolver trying to resolve a NS Record sn.mynetname.net, but the domain was stored on mynetname.net, and it received a NXDOMAIN response then return nil, it should try until the server mynetname.net also response an error

Interesting. We’ll take a look. Thanks for filing the report!

Hello. I have the same problem on my side with domains for which each segment does not necessarily have NS records, which prevents any resolution. Would it be possible to manage this case?
