## 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.
