hello

Instance types: IPv6 is supported on all instance types, except C1, M1, M2, M3, and T1.

if you want ssh to a ec2 instance via public ip address：

1. Make ec2 accessible to the internet

• you MUST put your ec2 instance into a public subnet
• assign a public ip to it (a public ipv4 address or a ipv6 address).

2. Open the SSH port for your client (usually the 22 port)

for example：

1. check route table,ensure that your EC2 is on a public subnet
2. check you security group
3. ssh into you ec2(can accessible both public ipv4 and ipv4 )

my ec2 have a public ipv4 address and a ipv6 address
