The DDI market is composed of solutions that provide and/or manage internal DNS and DHCP services, along with IP address management (IPAM). DNS, or Domain Name System, is a hierarchical and decentralized naming system that translates human-readable domain names into machine-readable IP addresses. DHCP, or Dynamic Host Configuration Protocol, is a network management protocol that automatically assigns IP addresses and other network configuration parameters to devices on a network. IP Address Management (IPAM) is a method used to plan, track, and manage IP address spaces in a network. DDI solution helps improve the availability of critical IT infrastructure while reducing operational expenditures. Infrastructure and operations (I&O) personnel utilize DDI to improve management and integration between these critical services and to provide a structured, automated and secure workflow for basic network operations (for example, adding printers or servers, allocating IP ranges for new branches, and so on).
