Dear All,
I have a staic ip from my ISP provider and i have a web server too. I NAT the port 80 from my modem to the webserver and I can access my webserver from internet using typing my static ip. If my static ip is 122.67.xx.xx, then I need to type http://122.67.xx.xx. and i have a domain name mydomain.com pointed to this 122.67.xx.xx ip in my C-panel. I can ping mydomain.com from internet but if I type http://mydomain.com I am getting the following error from my browser Unable to determine IP address from host name for mydomain.com and
The dnsserver returned: Name Error: The domain name does not exist. Please help me

Your DNS has an "A" record for www but maybe it misses an empty "A" record.

bye
