what isn't working? Pinging it?
I pinged it and it says the ip address is: 72.5.175.90
Put that in the hosts file as:
127.0.0.1 72.5.175.90
127.0.0.1 dpweb.vendaregroup.com
127.0.0.1
www.vendaregroup.com
127.0.0.1 vendaregroup.com
see if that works (put it in and then type in the site's url and see if you can get there or not).
