Does Lambda@Edge support IPv6 connectivity?

A Lambda@Edge function should be able to make HTTP(s) calls to EC2 instances using IPv6 addresses.

• Ensure the Lambda function is configured to use the latest Node.js runtime version which supports IPv6. Older versions may have issues.
• When making the HTTP request, specify the IPv6 address as the hostname and set the familyoption to 6 to force IPv6.

 var options = {
   hostname: 'xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx', 
   family: 6,
   //...
 };

• Make sure any security groups or network ACLs allow the relevant IPv6 traffic to reach the EC2 instance.
• Consider using an egress-only internet gateway to allow outbound IPv6 traffic from the instances without exposing them directly to the internet.
• Test connectivity from another IPv6-enabled resource first to verify the EC2 instance configuration before testing from Lambda.
