Node-whois is a WHOIS client for Node.js.
$ npm install node-whois
var whois =whois
You may pass an object in between the address and the callback function to tweak the behavior of the lookup function:
"server": "" // this can be a string ("host:port") or an object with host and port as its keys; leaving it empty makes lookup rely on servers.json"follow": 2 // number of times to follow redirects"timeout": 0 // socket timeout, excluding this doesn't override any default timeout value"verbose": false // setting this to true returns an array of responses from all servers
Contributions are welcome.
