The term “DDI” is an initialism of initialisms for DNS-DHCP-IPAM. While IPAM is last in the list, in reality, effective DDI starts with IPAM. Defining a DHCP pool or an A or AAAA record in DNS without an underlying IP address plan is like nailing a shingle to plywood without it being attached to the roof of a house. The house must be constructed first, on a solid foundation to boot. IPAM serves as the foundation for your IP address plan from which subnets, IP address pools and DNS resource records can be provisioned. Learn how you can devise and manage a solid IP foundation for your DDI tasks.
