+Description
+-----------
+
+For IPv4 addresses, the input string represents numbers in the Internet
+standard "." notation. IPv6 addresses are indicated as strings using ":"
+characters separating octets, with numerous caveats for shortcutting
+(see RFC #1884). If the NSPR library and the host are configured to
+support IPv6, both formats are supported. Otherwise, use of anything
+other than IPv4 dotted notation results in an error.
