The GSLB ServerIron uses the Internet Assigned Numbers Authority's (IANA's) IP address prefixes
(IPv4 or IPv6) to generate an initial static database of geographic prefixes. This database consists
of IP address prefixes (IP address/prefix length) and their corresponding geographic locations
(such as, the continent for each IP address prefix).

The following geographic prefixes are preconfigured:
