Which WAF Editions in Which Regions Support IPv6 Protection?

WAF supports IPv6 protection.

In cloud CNAME access mode, you can purchase professional or platinum edition WAF to protect IPv6 addresses.
In dedicated or cloud ELB access mode, EIPs are bound to the load balancers configured for WAF instances. If the load balancers support IPv6 addresses, the corresponding WAF instances also support IPv6 addresses

WAF can inspect requests that use both IPv4 and IPv6 addresses for the same domain name.
For web services that still use the IPv4 protocol stack, WAF uses the NAT64 mechanism to translate external IPv6 access traffic to internal IPv4 traffic. NAT64 is an IPv6 conversion mechanism that enables communication between IPv6 and IPv4 hosts using a form of network address translation (NAT).
For regions that support IPv6 protection, see Functions.
