If you want to test the IP address associated with your domain name (or indeed, any domain name) you can use a Ping tool. If you're not familiar with this tool then you can use a public Ping Gateway provided in the 'tools' section of the member's area or the following link. http://www.dnsstuff.com.  Assuming you visited the Ping Gateway at the end of that link, you would type in the domain name you want to test in the "Host name:" box (don't put www. just the domain name and extension e.g. domain.com) - all other settings can be left at their default values. In the results you'll see a whole lot of techie stuff, plus you'll see an entry under the "Answer From" heading - that's the IP address associated with that domain name.
