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

If the client has Java installed, you could do something like this:

ipAddress = java.net.InetAddress.getLocalHost().getHostAddress();

Other than that, you will probably have to use a server side script.
