Importing Subnet Data

Hi,

We own several class B networks, and are responsible for tracking allocations of subnets to our various business units. Most do not have any hosts within them that we track, although we may start to do this in the future.

We have the subnet data in an Oracle Database, the subnets are in a single field in CIDR notation. so x.x.x.x/32 for example.

I have no issue splitting out the subnet bit, and/or converting it to decimal 255.255.255.x format.

However when I attempt to import the data as an xls file, I noticed nowhere is there a field for subnet-mask?

Could someone explain to me how to import this subnet data, without any accompanying hosts in the data set?

Thanks very much

-Chris

Hello Chris,

The import feature reads in IP addresses from spreadsheets, and then tacks on a workflow to add the subnets from the IPs imported.

How many individual subnets are you bringing into IPAM?

Is it possible to discover subnets using seed router(s)? I am not seeing that feature in the documentation at all.

I see where I can do a network discovery using a seed router and it actually picks up a bunch of subnet from that router during the setup for discovery of the hosts.

No, not from IPAM, you cannot currently do this. This is an item we have on the roadmap for a future release

So essentially, I will have to manually add my subnets. That means that if and when I create new subnets, the IPAM will have to be manually updated. Is that the case?

We manage a relatively large network and if the software does not automatically discover new nets then what is the point? Any idea on how soon before that feature becomes available?

What are you using today for IP Address Management? What would you be importing from? How many subnets do you have?

So couple things:

We can import from the IP Address Management in toolset
