My public IP is in IPv6 format.
I want to whitelist it in the security group inbound rule.I added it as usual like this :
But it doesn't work for some reason. I tried converting it to IPv4 and added that but still cannot access. What am I doing wrong please help.
Is your VPC setup to use IPv6 and does the subnet your instance resides in have an IPv6 range attached to it?
You will also need to ensure your VPC has a route in the route table of your instance to allow ::/0 outbound for the internet (over an internet gateway as your instance is public).
Assuming all of these exist use DIG against the hostname you are connecting to, to validate it has an AAAA record to allow the domain to resolve for IPv6 addresses.
Here is some more information about setting up IPv6 for your VPC.
For IPV6 to be whitelisted and accessed anywhere for specific port just enter ::/0 in the source field.
for opening Porte 80
port: 80 Source:0.0.0.0/0 (for ipv4)
port: 80 Source: ::/0 (for ipv6)
