[As of 1.3](http://book.cakephp.org/view/1581/Miscellaneous),
CakePHP covers IPv6 validation out of the box, and you could probably
just store those addresses as `varchars` in your database and be done with it.
But that won't let you do calculations like looking up free addresses
inside a range.
The best way to store an IPv6 would probably be to use an 128bit integer, but
MySQL does not support this, and I haven't found any
[plans of doing so](http://bugs.mysql.com/bug.php?id=3318).
[mysql-udf-ipv6](https://bitbucket.org/watchmouse/mysql-udf-ipv6/)
involves compiling, making your app less portable.
Then there are [several hacks](http://www.koopman.me/2008/04/storing-ipv6-ips-in-mysql/)
possible.
I finally decided to do a PHP implementation cause app servers scale better than
dbs. I only use raw sql when it's strictly necessary, e.g. when doing full searches.
## Usage example
array(
'field_address' => 'address',
'field_bits' => 'bits',
'field_size' => 'size',
),
);
}
The `size` field will be automatically set whenever a user changes the `bits` field,
so you can hide it from the interface. But it's useful when you're trying to find
to which range an IPv6 ip belongs.
