/**
|
||
|
|
Creates an `IPv6Address` object from an IPv6 address as a string. If
|
||
|
|
the prefix length is omitted, it defaults to 64. The parser is limited
|
||
|
|
to the first two versions of IPv6 addresses addressed in RFC 4291.
|
||
|
|
The form "x:x:x:x:x:x:d.d.d.d" is not yet implemented. Addresses are
|
||
|
|
NOT compressed, so they are not always the same as the canonical text
|
||
|
|
representation of IPv6 addresses defined in RFC 5952.
