IPAM management solution you asked?

Level 10

In my previous post I wrote it seems that the consensus is what I would have expected on IP address management. I myself have experienced these same tedious tasks in regards to assigning IP addresses on the network; which I must say is VERY tedious. So how do we get around these tedious tasks to ensure consistency and a source of truth on the network? As a few comments mentioned; Infoblox, Windows 2012 IPAM management and as well Solarwinds IPAM module are possible solutions. I have personally used each of these except Infoblox. I have looked into the Infoblox solution and it seems to be pretty good however for the most part it is overkill in my opinion. I spent a good bit of time setting up and testing the Windows 2012 IPAM management but it was a bit complicated and cumbersome for the most part. Seemed to me it should be a little easier to setup and configure. But then again, maybe it was just a lack of configuration ease on my part. I have also setup and used the Solarwinds IPAM module and it is very solid and easy to setup and configure. Once you have your DNS/DHCP servers added as managed nodes into Solarwinds, discover them as DNS/DHCP servers; you can then head over to the IPAM module and start the integration pieces. You have the ability to create subnets and supernets; and then the IPAM module will auto discover via network scans and DNS/DHCP zone lookups and begin filling in the zone information. Now if you have the luxury of assigning IP addresses using DHCP then this is pretty easy to keep track of obviously. But if you still have to assign IP addresses statically then you can easily drill into the subnet within the IPAM module and find an available IP that has not already been assigned and assign and create your DNS name there. This will ensure that no one else tries to assign the same address to another device; assuming that everyone goes to the one single source of truth for assignments. This solution makes this tedious time consuming task much simpler and consistent. So I challenge you to at least give it a shot and see if one of these solutions does not make your IP address management much easier and free your time up for other tasks of the day.

At a previous employer, I fought this battle and lost. In the network group, we lacked the knowledge to fully understand what was needed for AD integration, and our server group didn't consider this a priority.

Good information as we are just heading down this path.  The IP Spreadsheet is getting unwieldly and we need something better.

We use solarwinds IPAM and have been for quite some time.  It's very accurate for the most part, and has replaced almost all of our spreadsheets.  The only one that remains is our VLAN / IP Subnet allocation spreadsheet, which I'm not really sure how to put into IPAM.  We use it to track what IP spaces are assigned where and what VLAN ID is assigned to a subnet.  Any ideas would be great, as the spreadsheet is somewhat annoying to use.

Having a solution is a lot easier than trying to remediate your duplications. Also the documentation is your resource to know that you are using all available resources and not over provisioning on either side of the fence.

That's what I am hoping for when we get to that point with an IPAM solution.

K, I would have jumped by now. Even if just off the chair. Good luck and Fast Pings to that resolution!

When creating the subnet in IPAM, there is a VLAN ID field, they can be set there.  If you're importing your subnets from a DHCP scope, you can still edit the information, just remember to use the edit option on the subnet level, not inside the subnet.

Our college campus has very tight budgets, especially now with overall student enrollment declining and concerns of what money will become available in the coming years from the state legislature.  I have tried for a few years to get an IPAM solution to eliminate the spreadsheets, but couldn't get the money approved for something like the SolarWinds IPAM.  We are currently implementing the Windows Server 2012 R2 version since it is basically an extra no cost add on for an existing server install.  It is good for the DHCP pieces, very clunky for the static IP addresses which is all of our servers, switches and a number of other devices.  It has not replaced the spreadsheet yet.

The lack of a write API has essentially killed the product here :/  I'm actively evaluating alternative IPAM solutions.

It would be nice if SolarWinds offered an IPAM lite where companies could install a licensed version where the limitations were on the number of networks and IP Addresses which could be tracked.  This would allow companies to start using the software for a greater period than evaluation software, see the benefit, get hooked and make the purchase.  Ninety day evaluations is often not enough time to sell a product to those who hold the purse strings.

@tcbene - I would definitely have to agree with you on this one. As suggested a lite version or community edition would be great.

I have only setup the Solarwinds IPAM and haven't used it much on a daily basis. Seems like a decent product and much better than a spreadsheet.

I have used Infoblox daily in my previous $dayjob. While it is expensive, if you use it for IPAM, DNS, and DHCP it is worth it's weight. The key with Infoblox is that everything is in one console and it keeps everything sync'd. Also they have an API that you can write applications/script against. In that previous $dayjob we went through a IP address change throughout the entire enterprise. When we started it took an hour or so to change all of the static DHCP assignments. I took a day to assemble a PERL script against the Infoblox API and at the time of cutover for a site, it took about 5 minutes to make all of the changes. That API saved so much time, effort, and errors.

If you are looking for an open-source solution I would highly recommend looking at phpipam. This is a very solid solution and fairly straight forward to setup.

You could also consider http://maas.io which has IPAM functionality in 2.0 along with bare metal provisioning.
