iphone app bundle / company identifier with ccTLD - what's the protocol?

Question

whats the protocol when your domain name is

domainname.com.au

is it

au.com.domainname.app_id

or

com.au.domainname.app_id

or possibly

com.domainname.app_id

Bascially what do you do if you have a country code top level domain (ccTLD) and you want to start cranking out iPhone apps?

merci!

Answer 1

It should be au.com.domainname.app_id.

If you swapped the au and the com, then you could conflict with an app from the au.com domain.

If you omit the au, then you could conflict with an app from the domainname.com domain.

By always reversing your FQDN, you insure against conflicts like that.
