Originally created by @soamz on GitHub (Nov 18, 2016).

Okay, we are a ISP and we have 200 private devices all in 10.10.12.xx IP addresses.

We simply need to add each device here and specify its IP as 10.10.12.x and make sure, the device and the IP shows.

But Im confused about the workflow al together for the IP.

When i goto IP, it asks me to enter /xx , which I dont need.
It confuses the team if I enter 10.10.12.xx/32

I simply need it to manage show as DEVICE ABC - 10.10.12.125

Simple.

How to achieve or what am I missing ?

The mask is part of the IP address. You cannot configure an IP address on an interface without also specifying a mask.

Okay whats the workflow then ?

How should I manage the IP addresses stitched to the devices ?

if you put the ip as 10.10.12.125/24 and set the flag to make it the primary IP, only the IP will show up in the devices list.

the subnet is an integral part of the ip and must be included. sounds like you just need to define one prefix: 10.10.12.0/24, then every ip you assign will be part of that prefix

Okay lets say I want to search which device has 10.10.12.212 IP, how will I find it out with one search click ?

not sure if it can be done faster, but this works just fine for us:

click search, it pulls up the ip, which is linked to the device

Can you show me your devices page and IP page ?

Im confused completely.

You said, we cannot show as DEVICE A - 10.10.12.24 etc

This is the result of searching specifically for ip 10.250.100.1

image

and this is what my device listing looks like when sorted for just that device (not trying to expose too much of our internal info

@lbegnaud I recognize that data center. I knew with a name like that, you had to be from the same area as me.

It shows /24 , means whole block for one device ?
How confusing ?

Can someone share some video or screenshots ?

Im still lost about how to see my specific devices with specific IP addresses and not with subnet mask.

@soamz hopefully this can help:
If you're using a subnetmask of 255.255.255.0, that is represented by /24 on the end of the IP Address.

Example: If I want to add 10.10.12.125 as part of the 10.10.12.xx network, I'd enter it as 10.10.12.125/24

If you're tracking all of the IPs in the 10.10.12.xxx network, you'd then create a Prefix for it:
image
The IP addresses you entered with the /24 notation will all show up under the prefix
image
The Prefix is handy because you can look at all of the IP addresses within a network.

If you prefer to not group them by prefix at all, and have each IP address be an individual network, you would use a /32 (255.255.255.255) notation.

Yes I was thinking to put all devices with /32 as /24 will confuse my teams.

This seems a clear explanation.
I will be checking tomorrow and see if I can organize the devices well.
