When you specify a CIDR range, start with the first IP address in the range. They can also provide platforms to create Network Load Balancer which will give you a single IP address via which all the external IP address will be forwarded to you Services. A Pod represents a set of running containers on your cluster. Cloudflare requests will always come from a defined range of IP addresses (documented here), and you can add those ranges to a security group on your AWS load balancer.This does not change the X-forwarded-For, CF-Connecting-IP or True-Client-IP headers you are already using to audit and track users. As part of today’s launch, each target group now has a target type attribute: instance – Targets are registered by way of EC2 instance IDs, as before. These addresses can be in the same VPC as the ALB, a peer VPC in the same region, on an EC2 instance connected to a VPC by way of ClassicLink, or on on-premises resources at the other end of a VPN connection or AWS Direct Connect connection.
