This is a lightweight DNS cache with configurable TTL.
The cache will increase performance and eliminate DNS lookup conflicts.
$ npm install dns-cache
For Node.js 0.10 and older, user dns-cache version 1.0.0.
Dns-cache 2.0.0 is not backwards compatible with the changes introduced to dns.lookup in Node.js version 0.12.
Just require dns-cache on application start.
var dnscache = require('dns-cache')(10000);
All following DNS look-ups will be cached and re-used automatically.
Takes optional TTL in milliseconds as the only configration argument.
