Ok let me get this straight but you would like com.domainname
jk but from your thread title and question .com – this is the most popular and desirable extension for domain names.
If the domain name with a .com extension is available you would start with that one and go with other extensions if you want from there.
The .com extension was the first one used to represent online commercial enterprises, and is the one people most commonly associate with web sites.
At one time and I am pretty sure its the same now unless the search engines have taken over your browser, if you had a domain with a .net .org .ca .org .edu or a .com extension, you type yourdomain in your browser with no extension it will default to the .com domain first,
hope this helps
