Comment (by Ipstenu):

 From #41721

 > Hello,
 >I am trying to connect to a remote database using IPv6. I have configured
 the MySQL database bind address to that of the IPv6 address and created a
 database and issued all the required permissions.
 >When I go to install WordPress, I enter the IPv6 address and WordPress
 returns the following message "Error establishing a database connection".
 I have made sure my MySQL is working by using MySQL Client and it connects
 to the database without any problems.
 >I then did a little more digging and found that if I change the database
 bind address to a IPv4 address and configure the correct permissions,
 WordPress will install using an IPv4 address.
 >WordPress will not work with IPv6 address.
 >Thanks.
