Simplify ALB’s public IP address assignment with VPC IPAM

Networking & Content Delivery Blog



The article discusses AWS's new integration of Application Load Balancers (ALBs) with VPC IP Address Manager (IPAM), which allows predictable public IP address assignment for internet-facing load balancers.

  • Enables use of deterministic IP addresses for ALBs
  • Supports Bring Your Own IP (BYOIP) addresses
  • Helps reduce Amazon-provided public IPv4 address costs
  • Facilitates consistent IP allowlists with external partners
  • Works with dual-stack IPv4 and IPv6 configurations

Key benefits include simplified IP management, cost reduction, and improved external partner integration by providing predictable public IP addresses for internet-facing load balancers.
