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.
Here is our list of the eight best IPAMs to manage IP addresses:
- SolarWinds IP Address Manager – EDITOR’S CHOICE This flexible on-premises package is an IPAM but it also has integrated DHCP and DNS servers built in to create a full DDI solution. You can also choose to use third-party or native Microsoft DHCP and DNS systems with this tool. Runs on Windows Server. Start a 30-day free trial.
- BlueCat Address Manager This IPAM is part of a full DDI solution and it offers the option to create an overlay network address strategy that can feed through an SD-WAN system to integrate multiple sites and cloud platforms into a single network. This is a cloud-based service.
- Infoblox IP Address Manager This IPAM is part of a DDI package that is delivered as a SaaS solution and will be of particular interest to multi-site businesses.
- The NOC Project This is an Operational Support System that includes much more than just an IPAM. The package has a DNS server but no GHCP server; it includes routing and network management support. This is a free package that installs on Linux and FreeBSD.
- BT Diamond IP This is a virtual appliance that runs on a cloud platform or on site over Hyper-V or VMWare and connects through to associated DHCP and DNS servers.

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 paid or free IPAM software. 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.
Our methodology for selecting an IP address management tool
We reviewed the market for IPAMs and analyzed options based on the following criteria:
- An IPAM that is bundled in with DHCP and DNS servers or can interact with third-party servers.
- An IP address scanner that can be set to run continuously or on a schedule
- On demand IP address scanning
- Exportable results for analysis in other systems
- Options to manage SD-WAN overlay networks
- A free trial or a demo system for an opportunity to assess the tool before buying
- Value for money from an IPAM that provides a competent service at a reasonable price
With these selection criteria in mind, we identified a number of reliable IP address management systems and we made sure to include some free options.
SolarWinds IPAM is a DDI solution. It integrates DHCP, DNS into a single platform. With it, you can manage and track DHCP and DNS services in real time, alongside with traditional IP address management. SolarWinds IPAM supports many DHCP/DNS vendors on-premises and cloud deployments.

IP address management FAQs
Why is IP address management important?
Each device on a network has to be identified by a unique IP address in order to communicate through a router across links – link-level communication through switches is managed with MAC addresses. If a device does not have an IP address, other devices on the network cannot contact it. If two devices have the same IP address, it would be impossible for the router to know which of the two devices another device on the network is trying to contact. IP addresses are assigned by a DHCP server on a lease. When a lease expires, the address needs to be renewed. IP address managers poll the network to see which IP addresses are still in use. This list enables the DHCP server to update its records of available IP addresses.
What is the difference between DHCP and IPAM?
DHCP is the Dynamic Host Configuration Protocol and a DHCP server is in charge of allocating IP addresses to devices on a network for a period on a lease. IPAM is an IP addrdsss manager. It checks across the network to see which IP addresses are currently in use. Feeding the IPAM list into the DHCP server lets DHCP know which IP addresses have been abandoned and can be returned to the pool of available addresses for reuse.
Can 2 devices have the same IP address?
Each device has to have an IP address that is unique within an address space. Thus, each device on a private network has to have an IP address that is unique within that network. However, that same IP address can be deployed for another device on a separate network. This is because those two devices will never be subject to the same router. Every device on the internet has to have an address that is unique throughout the internet. As private networks connect to the internet through a gateway, the network is represented by the gateway, which has an IP address and the devices behind them are not directly contactable. If two devices on the same network have the same IP address, it would be impossible for the router to know to which of those devices it should send messages that are tagged with that address.
