How to diagram a dhcp server

I just inhereted a class B DHCP server on windows 2008 R2.  I was told that we were breaking out blocks of IPs based on subnets through the use of the third octet.

Is there any scripts, reports, or apps that I can run, that will tell me in some form of tabular format the first/last IP and subnet of each block that has been assigned in a windows DCHP server?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

If you have a Windows 2012 or Windows 8.1 system, you can use the export-dhcpserver powershell cmdlet.  It exports to XML format, and will export from Windows 2008 servers.

I wish, but I'm not there yet.  Network is win7 and server 2008.....what else you got?
btw, I am grabbing that page for after migrations this year.
Well, there's also a netsh command to back up the DHCP database.

The export isn't very human readable, though.

That's all I've got.  You might be able to find a third-party IPAM (IP Address Management) tool that will work for you.
