A UCC Certificate can:

• Secure up to 500 entries (first 3 non-wildcard entries are free, additional charge per entry after the 3rd entry)
• Be used on unlimited servers concurrently
• Have its entries changed at anytime or may be specified later without fees or costs
• Have entries that are a Fully Qualified Domain Name (Example: SSL.com) (FQDN)
• Have wildcard domain name entries with a single level (i.e. *.domain.com, but NOT multiple levels like *.*.domain.com)
• Be used on unlimited IP addresses with multiple, concurrent private keys (great for hosting and virtual hosts)
