Enabled empty responses

[tsndr]

If a zone exists but no records was set, it will always respond the SOA record, which is (compared to bind) the wrong behaviour. So i would push this answer instead:

res.answer.push({ name: question.name, type: question.type, data: null });

With my changes it's possible to return an empty response if the data attribute is set to null.
I hope its helpful 😊

Hi tsndr,

It is helpful.

Please keep in mind that the DNS protocol has a special flag (NXDOMAIN) that must be set for empty responses.

I have had the same issue 2 years ago, see #5 but this project is not maintained any more.

Cheers, fogs

Hi fogs,

thanks for the answer 😊

What do you think about a nodejs bade dns server in general? Only for testing or production ready? And what about the performance compared to bind, could it ever hold up?

Cheers,
Tobi 😊

If you are interested in availability, scalability, security, then choose one of the big and mature servers. PowerDNS rocks. If you like to play with the protocol, use it for stuff it was never intended to and don't think it hurts to learn more about DNS, there is no better way than building your own. We did both.

Cheers mate!

Ach. Und Grüße nach Remagen.

I've never heard of PowerDNS, I might look into that 😊
I am using bind right now, but maybe I'll switch, we'll see 😉

Viele Grüße nach Hamburg 😊
