Applying ITIL4 to IP address management
The discipline of network management affords innumerable technical and business benefits to organizations via the centralization of control, monitoring, and provisioning of distributed network elements such as routers and application or services databases. These benefits include holistic management of the entire network from a centralized point where appropriate resources and expertise can be leveraged for troubleshooting, resolution, and escalation. This pan-network approach lends itself well to supporting structured network change control procedures and is even more crucial today with enterprise networks expanding into clouds, IoT subnetworks, and mobile networks.
