The GSLB ADX 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).
IPv4
The following geographic prefixes are preconfigured:
