The IP address space is the backbone for the modern enterprise. It’s essential for the hands-on IT professional to be on the lookout for conditions that could be detrimental.
What is IPAM?
The IP address space is the backbone for the modern enterprise. Without proper management of the IP address space, resources across the enterprise can become unavailable. It’s essential to maintain optimal IP space functionality. IP Address Management (IPAM) tools are designed to provide a deep level of visibility in the IP space while automating common IP space management tasks such as discovery and inventory.
Best Practices for IPAM
Captured below are the key areas a good IPAM solution should effectively cover. Focusing on these areas when evaluating IPAM products will ensure you select an enterprise-ready IPAM solution that suits your needs both today and tomorrow.
Up-to-date visibility requires error-free, automated discovery & inventory of all or part of the IP space on a customized interval that best
suits the granular needs of each subnet.
The IP space and its supportive subnets are dynamic. Rollouts and expansions, can cause a subnet scope to fill unexpectedly. It’s essential the administrator be alerted to IP space events such as DHCP scope exhaustion.
Out-of-the-box reports should include Managed IP Addresses, Available IP Addresses, Duplicate IP Addresses, and DHCP Leases.
IPv6 adds a new layer of complexity to the IP space. Support for IPv6 allows you to know which devices are dual stack capable and where IPv6 is
deployed on your network.
Correlating IP addresses with MAC addresses and hostnames enables an administrator to understand how certain properties have changed retrospectively.
