What is the best way to set the domain name up so that all hostnames, nameservers etc resolve properly. The name is registered with godaddy at present.
If you’re using a cPanel host, then merely use the AddOn domains and add the second and third domains to the main domain. These will be setup in subdirectories of the main domain but fear not, they will resolve as fully qualified domains.
Okay, a subdomain is treated much the same way except that it used the main domain’s … well, domain. Subdomains also typically reside in a subdirectory of a main domain BUT, as with the AddOn domain, requests of the subdomain should bypass the DocumentRoot of the main domain.
