IPAM? What is it and How to Use it to Manage IP Address & DHCP


Marc Wilson

Managing Hundreds, if not Thousands, of IP connected devices can be a big pain – But imagine trying to keep track of which IP Address is assigned to each device, which the dhcp lease is up or when the IP has changed?

Well your in Luck, as there is a solution to managing IP addressing tracking issues just like the one above.

This is what we call IPAM Solution.

What is IPAM?

Internet Protocol Address Management, or IPAM, is a procedure for organizing, tracking, and adjusting the information related to the IP addressing space. It can help a network admins guarantee that the list of IP addresses remains updated.

It can be an inventory of the used and unassigned IP addresses, their subnets, their status, host name information, and even what hardware is associated with it. Normally, an IPAM integrates to DHCP and DNS to allow even more precise information.

Why is IPAM Important?

We live in a world that is highly dependent on IP addressing. From personal to enterprise-sized networks, IP addresses are essential for communication. If it is connected to a network, any device depends on its address. On top of that, emerging technologies such as IoT, Cloud Computing, and wearable devices are increasing the demand for IP addressing space.

We need efficient IPAM to help us manage, plan, and track all our IP addresses.

Getting by Without an IPAM

Some businesses seem to get by without IPAM. Their IT departments are managing IPs with the help of spreadsheets and documents. A spreadsheet with an IP addressing scheme may contain information such as, IP addresses, subnets, VLANs, connected devices, and even switch port numbers.

When the network admins are planning and executing an IP addressing re-assignment or expansion they will take this document and modify it with the new information. In order to avoid any IP address conflict, the admins check this document when assigning IP addresses to new devices and communicate it with the rest of the team.

An example of an IP spreadsheet?

But it gets really challenging when trying to update this spreadsheet. Pinging an IP just to confirm that the destination is “no reply”, doesn’t really tells you much about the other end. Maybe there is a device using an IP, but it just happens to be momentarily out of the network.

But checking and updating a spreadsheet every time has the following major flaws…

  • Frequent IP address Conflicts
    In some cases when a DHCP is not configured properly, it can dynamically assign reserved IP Addresses to devices plugged into the network. In the same case, an IT team member might assign the same IP address, statically, to a new critical device. Creating a duplicate use of the address and making both devices unavailable. These conflicts in IP addresses can create massive outages, which is particularly harmful in large networks.
  • Higher risk to Security Breaches
    A simple spreadsheet has no value for security audits. Without knowing which IP addresses are assigned to which device, when they were assigned, and to which particular user, there is a higher risk to a security breach.
  • Tougher to Remain Compliant
    Some regulatory compliance requires IP assignment logs and reports. This calls for extremely well-organized documentation and logging procedure in part from the network managers.
  • Troubleshooting Time
    When problems occur and the spreadsheet is not updated properly, troubleshooting becomes complex. If the network faced a temporary outage, it could be due to a cabling problem, port mismatch, IP address conflict, or a breach in security.


With a million dollars of infrastructure in play, it seems illogical to try to “cope” with a spreadsheet and the communication from your IT team. When rolling out new IT equipment or troubleshooting network issues, you want to be 100% confident that the IP addressing design is accurate.

Popular “IPAM” Solutions

Fortunately, you can leave the spreadsheet behind and implement a comprehensive IP management solution.

Modern IPAM solutions call for management capabilities far beyond traditional IPAM. Some services provide what is known as a DDI or “DHCP, DNS, and IPAM” bundled into one tool. Services such as DHCP and DNS are critical components for good IP management.
