@Code9988 Why do you want to open ports?. If you are getting nat type 2/ open or moderate in games, port forwarding is not necessary. It ain't gonna change ur gameplay experience.
@tatyasky Ps4 doesn't support ipv6, but
netflix app supports it.
Ps5 does support it, but it's not used for online gaming, download or some other stuff. Only netflix app uses it in ps4/ps5. Only difference is that ps4 doesn't show ipv6 details in settings, but ps5 shows it, but not of much use.
