Glossary
DDI —along with its component parts DNS, DHCP, and IPAM— occupies a curious corner of the technology universe. It is essential, foundational, and quietly responsible for keeping vast digital ecosystems from descending into complete chaos, yet it is also a domain where terminology has evolved in… creative ways. Different vendors use the same words to mean different things, different words to mean the same thing, and occasionally invent entirely new ones for reasons best left unexplored.
This glossary exists to bring a small but meaningful amount of order to that confusion. Its purpose is not to declare a single “correct” definition for every term, but to provide clear, practical explanations that help you navigate the DDI landscape with greater confidence and fewer raised eyebrows. Whether you are new to the space or have been living in it for years, consider this your calmly written guide to a system that is far more important —and occasionally more perplexing— than it first appears.
