Can I perform a DNS lookup (hostname to IP address) using client-side Javascript?

Question

I would like to use client-side Javascript to perform a DNS lookup (hostname to IP address) as seen from the client\'s computer. Is that possible?

Answer 1

My version is like this:

php on my server:

jQuery on the page:

var self = this;
$.ajax({
    url: this.url + "getip.php",
    data: null,
    type: 'GET',
    crossDomain: true,
    dataType: 'jsonp'

}).done( function( json ) {

    self.ip = json;

});

It works cross domain. It could use a status check. Working on that.
