Top Open Source IP Address Management Software

In this post you will find top open source software for IP address management (IPAM). If you are sysadmin at organization that holds pool of IP addresses and allocates its parts to clients then you must use IP address management tools to track used, reserved, allocated or free IP addresses. It usually prevents an overhead and allows to have clear picture of IP addresses resources usage within an organization on the whole. For example, it may be useful to know how many free IP networks are available for clients and take necessary actions before it happens there’s nothing to allocate. IP address management tools may also make it possible for you as a sysadmin to prevent fragmentation of IP addresses usage. Generally if you work at LIR then IP address management tool is a must.


IPplan (formerly known as iptrack) provides clean web interface for IP address management with wide range of features like IPv6 support, multi-language  interface, split and join of IP networks, import from routing tables and XML/CVS files, multiple user groups, overlapping detection, search, audit, triggers and much more. IPplan stores its data in databases like Postgresq, Mysql or Oracle. Moreover IPplan provides API so you can create DHCP configs (for example) based on IPplan’s database.

GestioIP is lively maintained IPAM system available under GPLv3 license. It provides web interface for IPv4 and IPv6 tracking, allows network discovering, search, filtering, splitting/joining of IP networks, statistics, embedded IP calc and much more. I would recommend GestióIP to those who need clean and simple IPAM with basic features. Btw, Gestió in Catalan means “management”.
