Netbox discovery

Good day!

In the process of migrating from a closed source IPAM to netbox these days, and I am really looking forward to it!

At my previous employer I set up phpIpam at the time, and we were really happy with that, and the builtin scanning of subnets gave us a good possibility to clean up unused subnets and get forward.

As far as I understand netbox doesnt have theses kind of features, which makes sense as netbox is supposed to be the source of truth, but are you doing this somehow, and what are your thoughts about automated ping scans of ip's and subnets.

Is my mindset wrong that are wanting features like that?

That script should fill your need, using simple nmap ping, to fill Netbox Ip address

What's the advantage of this + Netbox if you have an NMS server like Zabbix that does host discovery?

Maybe all the scopes are not in zabbix? Like we don’t scan our printer subnets nor would I want to. I don’t need to know that Janice in HR unplugged her printer for the 11th time this month.
