With addon domain names you can host multiple domain names/sites with a distinct content on a single hosting account. The addon domain names usually are pointed to some folder on your web space and open a differnt website from your main site. With most web hosting providers you can have separate email accounts for the addon domain. The only downside is that you do not have a separate Control panel for the addon domain.

4 – read for group
4 – read for others

7 (2+4+1) write, read, execute for owner
5 (4+1) read and execute for group
