This init extracts an IPV6 address, and, if applicable, TCP port, from a given string.

The definition of an IPV6 address is: XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX

Where X is 0…F (hexadecimal). There are shortcuts (discussed below), but we assume leading zeroes, and all zeores are represented.

Each segment is a positive integer, from 0 - 65535 (FFFF in hexadecimal).

If there is an additional TCP port, then the IP address is bracketed, and followed immediately by a colon (:), then immediately by a positive integer, like this: [XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX]:Y

Where Y is a positive integer

SHORTCUTS:

You can specify a range of 0-filled elements by using :: as a shortcut. This is only allowed once in the entire address, so:

XXXX:0000:0000:0000:XXXX:0000:0000:XXXX can be written as XXXX::XXXX:0000:0000:XXXX or XXXX:0000:0000:0000:XXXX::XXXX

Usually, the first shortcut will be selected, as it’s the longest range.

You can have a maximum of four (4) hexadecimal characters in an element. Case of the hex digits is usually lowercased, as a convention, but uppercased is allowed. We use lowercase.

You cannot have characters other than 0-9, a-f (or A-F) in an element.

You must separate elements with colons (:). If you are specifying a port, you must wrap the address in brackets ([]). You must have BOTH brackets if you are wrapping the address.

You can wrap an address in brackets, even if you do not specify a port.

If you specify a port, it must appear after a colon (:), after the closing bracket (]), so you would have ]:12345, to specify TCP Port 12345.

You can have a maximum of eight (8) elements.

Illegal formats and syntax errors result in no address being set. This method does not guess.
