I have ComCast Business Class with a static ip address. I am allowed 1 domain name with them and want to make that my main portal. This part is working as www.inwoon.net. I want to add the subdomains ns1 and ns2 respectively so I can let the user set their DNS to ns1.inwoon.net and ns2.inwoon.net. Help I am stuck on how to set my Master DNS record at ComCast to pass through all requests to the web sites registered with me. I know it is fairly easy but the DNS manual is scary. Any help is greatly appreciated.
