How To Configure IPAM in Windows Server 2016

IP Address Management (IPAM) is a feature that allows you to manage infrastructure servers such as DHCP, DNS, NPS, and DC servers from a centralized location. IPAM also supports the automatic discovery of infrastructure servers of your Active Directory forest. Since it supports the DHCP server management, hence you can manage and track your dynamic and static IPv4 and IPv6 address space centrally. In this post, we will explain how to install and configure IPAM server in Windows Server 2016. The same steps can also be used to configure IPAM server in Windows Server 2012/R2.

Understanding IPAM Lab Setup

Before to configuring IPAM server, first, you need to understand the topology we are going to use. We have two servers named DC1.mcsalab.local and Server1.mcsalab.local. Both the servers are running on Windows Server 2016. Server1 is the member of mcsalab.local domain and will be configured as IPAM server. DC1 server has a pre-configured DHCP server that we will add and manage through the IPAM server.
