We currently have a domain name that is long and contains a hyphen. It isn't very easy to hand out to users because it doesn't just roll off the tongue.
There is another domain that we'd like to have, but someone already owns it. They don't seem to be using it though. The index page shows a directory listing and in there there is only a phpinfo() page. That page shows the server is running a very old version of PHP.
We've looked up the whois information and see that the domain doesn't expire for another 6 years, so someone is at least paying for the registration for long periods of time. We've reached out via the contact information in whois to see if they'd be willing to sell us the domain but there hasn't be a response.
Do we have other options to get the domain name? Obviously, we're not looking to do anything illegal. Reaching out the existing owner has either gotten us ignored or we are sending to an unmonitored email address, so that's almost as bad as ending up in a spam folder.
