dns-rcodes

Maps easy to remember names to DNS RCODE (response code) values.

Usage

var rcodes = require('dns-rcodes');

// Get the rcode for "No Error"
var noErrorCode = rcodes.NoError;

// How about if the lookup is "Refused"?
var refusedCode = rcodes.Refused;

// Doing TSIG? We got you...
var badSignatureCode = rcodes.BadSignature;
