How to make an IPv6 segment?

Hi everyone.

I want to compare the traffic using IPv4 and IPv6 for one website with Matomo.

After speaking with Matomo team, I have added two segments.
The first is for IPv4 with this rule: ‘Visitor IP’ lower than But the resulting test contains all traffic (IPv6 included).
And the second is for IPv6 with this rule: ‘Visitor IP’ greater than

But, the test result is empty.

I have visitors using IPv6 in my visitor journal.

How to configure this segment?
