lambaliciousIt's easier to remember the IPs of good DNSes, too.
You can still NAT IPv6
VictoriaYes, but why would you want to? We have enough addresses for the foreseeable future.
So you don’t need to change your network if your isp changes.
danYou can use ULAs (unique local addresses) or that purpose. Your devices can have a ULA IPv6 address that’s constant, and a public IPv6 that changes. Both can be assigned using SLAAC (no manual config required).
I do this because the /56 IPv6 range provided by my ISP is dynamic, and periodically changes.
Yes but you’d still be performing NAT. It’s at least 1:1.
You’ll need to deal with firewall rules regardless, and drop IPs into policies. IPv6 doesn’t remove any of those chores but gets rid of having to maintain tables to deal with many-to-one NAT.
You wouldn’t need NAT. The ULA is used on the internal network, and the public IP is for internet access. Neither of those need NAT.
What translates the public ip to the internal ip? Aren’t they different?
There’s no translation between them. With IPv6, one network interface can have multiple IPs. A ULA (internal IP) is only used on your local network. Any internet-connected devices will also have a public IPv6 address.
