does anyone know if three give a persistent prefix or one that changes periodically. I ask as need a reliable firewall rule based on a subnet/prefix. I understand CGNAT used for ipv4 but I don’t understand why ipv6 can’t be assigned in a sticky way to home users.

edit:

i am referring to my 5g home broadband connection from three and the ipv6 address I get.
