With the difference being that you get your own /48 or /56 and suffer from only your own behaviour.
If you're behind CG-NAT because your ISP can't get enough IPv4 addresses, then you suffer from the behaviour of other people.
- mrkurt 4y agoI don't know of a single ISP that gives /48s out to customers. Maybe a /56, but I think even that is rare. IPv6 is way better than cgnat, but ISPs are still doing their own internal routing for much smaller blocks. Meaning the block itself is functionally the equivalent of a shared IPv4 for abuse prevention purposes. But also, I could just not know about the ISPs giving out /48s. My window to this is from the abuse prevention side.
