Please add IPv6 blocking support

This is essential. So many of our orders list the customer’s IPv6 address, and there is no way to map to IPv4. All they have to do is use their secondary email address to bypass the block.

As requested over a year ago here: https://wordpress.org/support/topic/does-it-block-adress-on-ipv6-format/

Next should come wildcard support, so they can’t just switch devices in their home.

Thanks.
