Unable to pass IPv6 MySQL host

[joelvardy]

I am unable to specify an IPv6 address as the database hostname with the following command line arguments:

--db_host=2a01:7e00::xxxx:xxxx:xxxx:xxxx
--db_host="2a01:7e00::xxxx:xxxx:xxxx:xxxx"

Error received is:

Zend_Db_Adapter_Exception
 SQLSTATE[HY000] [2005] Unknown MySQL server host '2a01' (2)

An IPv4 address works as expected.

This was also an issue in Magento 1.x

Comment from @buskamuza :

Here is the problem - lib/internal/Magento/Framework/DB/Adapter/Pdo/Mysql.php:314

} else if (strpos($this->_config['host'], ':') !== false) {
list($this->_config['host'], $this->_config['port']) = explode(':', $this->_config['host']);
}
