  • Why: IPAM decisions are often irreversible and IP exhaustion is a recurring production wall. A structured treatment of IPAM modes, dual-stack, and the newer Extend Service IP Range feature is squarely on-topic.
  • What: A concepts-to-solutions tour of Kubernetes IPAM: CNI roles, IP assignment for pods/services/nodes, and current IPAM features. (from abstract only)
  • How: Covers IPAM modes, CIDR allocation/subnetting for IP exhaustion, dual-stack (IPv4/IPv6) complexities, connectivity troubleshooting, and the Extend Service IP Range capability. (from abstract only)
  • Where applicable: General Kubernetes networking design; broadly applicable. Leans introductory but earns a place for the strategic/irreversibility framing and the newer features.
