Suggestions for open source IPAM?

Hi all,

So my company is in dire need of an IPAM solution, and I'd like something that might be able to integrate with our current DNS (BIND) and ISC DHCP setup.

As an idea of scale, we probably have about 50 VLANs and somewhere around 3,000 hosts.

Does anyone have any good suggestions? For certain internal reasons, we cannot use either of the following:

• GPLv3
• No Infoblox solutions
