The very short answer to “What is DDI?” is that it stands for DNS, DHCP, and IP address management (IPAM). It is often used as a shorthand acronym to describe the integration of these three core components of networking into one management solution.
A DDI solution provides a centralized platform to manage DNS and DHCP services and has an IPAM component. In this post, we’ll look at the three components that comprise the DDI meaning. Furthermore, we’ll explore both the core benefits and some additional features of more robust DDI network solutions.
In order to define DDI, we must understand each leg of the triad that comprises it. In brief, DNS provides IP addresses, DHCP assigns IP addresses, and IPAM manages IP resources. Bringing these core DNS, DHCP, and IP address services together into one platform solution can transform network management.
Gartner first coined the DDI term to describe this enterprise solution. (Unfortunately, the world is still waiting for a DDI Magic Quadrant from Gartner.)
Domain Name System (DNS) is the phone book of the internet. It translates human-readable domain names that we easily remember, like bluecatnetworks.com, into IP addresses like 104.239.197.100, which are the language of the internet.
DNS allows computers, servers, and other networked devices, each with their unique IP addresses, to talk to each other. As a result, it gets users to the website they’re looking for. This semantic layer allows the internet to work more smoothly than something based only on numeric addresses.
Dynamic Host Configuration Protocol (DHCP) is the standard mechanism to dynamically assign IP addresses within a network. When a device such as a laptop or a smartphone joins a network, it typically asks for an IP address from a DHCP server.
Next, the server will quickly and automatically assign an IP address and some related parameters. Subsequently, once the device has accepted the assignment, it can communicate with both the internal network and the public internet.
IP address management (IPAM) is a method for planning, tracking, and managing IP address space on a network. If there are hundreds or thousands of connected devices on your enterprise network, imagine trying to keep track of each of their IP addresses yourself. It gets out of hand fast.
On the other hand, IPAM software tools can give network admins a real-time inventory of both used and unassigned IP addresses, including details like their subnets, status, hostname, and associated hardware.
On a lighter note, this isn’t the only thing that DDI stands for. Therefore, be sure you’re looking for the right definition. Our favorite might be the Bocas Islands between Trinidad and Venezuela, in the Bocas delDragón. Locally, Trinidadians refer to them as “down de islands,” or… DDI.
When DNS, DHCP, and IPAM are managed separately, there are inherent risks. However, with a centralized solution, network administrators get visibility and control of their network from a single pane of glass. Specifically, this gives administrators:
Since this solution is integrated, many tasks are simplified for the network team. Instead of having a gap between records and actual IP address usage, records are updated in real-time. For example, here is some of what you can do seamlessly:
Additionally, beyond maintenance tasks, DDI solutions include features that help organizations take core network services management to the next level. For instance, these can include:
