Node.js – Simple DNS Server in Node.JS? (Primary/Authoritative DNS Server) (maybe ndns?)

dnsndnsnode.js

Does anybody know of a DNS Server that is written in Node.JS? I am specifically interested in Authoritative DNS Servers (as opposed to caching DNS server).

The only thing this needs to do is to serve A, MX, TXT, SPF, SOA, NS records based on my own algorithm which I will write into a fork or clone of whatever I find to start with.

In fact I may not need all of those types of records. But the important thing is that it must work. I do not want to have DNS debugging issues. I am hoping (expecting) this will not be a problem because DNS is very simple (I have heard).

Is there anything in Node.JS I can start with? If you know that something has been used in production, then please let me know.

The Node.JS DNS Servers I have found are

dnsserver.js (alternate link)
ndns which has an extension called mdns
dns-server

If anyone is using one for production, I would like to know. So far they seem to be very scattered efforts.

How to find the authoritative name-server for a domain name

You'll want the SOA (Start of Authority) record for a given domain name, and this is how you accomplish it using the universally available nslookup command line tool:

command line> nslookup
> set querytype=soa
> stackoverflow.com
Server:         217.30.180.230
Address:        217.30.180.230#53

Non-authoritative answer:
stackoverflow.com
        origin = ns51.domaincontrol.com # ("primary name server" on Windows)
        mail addr = dns.jomax.net       # ("responsible mail addr" on Windows)
        serial = 2008041300
        refresh = 28800
        retry = 7200
        expire = 604800
        minimum = 86400
Authoritative answers can be found from:
stackoverflow.com       nameserver = ns52.domaincontrol.com.
stackoverflow.com       nameserver = ns51.domaincontrol.com.

The origin (or primary name server on Windows) line tells you that ns51.domaincontrol is the main name server for stackoverflow.com.

At the end of output all authoritative servers, including backup servers for the given domain, are listed.

Java – Simple Authoritative DNS Server in Java

George,

I guess what you need is a java library which implements DNS protocol. Take a look at dnsjava

This is very good in terms of complete spec coverage of all types of records and class.

But the issue which you might face with a java based library is performance. DNS servers would be expected to have a high throughput. But yes, you can solve that by throwing more hardware.

If performance is a concern for you , I would suggest to look into unbound
