Comodo Positive Multi-Domain SSL certificate was added specifically for anyone in need of securing many domains at the same time and to ease management. These are particularly popular with web hosting where many domains share the same IP address. The SSL certificate includes up to 3 domains and 2 of them can be changed at any time (requires reissue). It is possible to add more domains as needed.
Please note that domains in the SSL certificate does not cover www as well (only the domains you specify).
