nu_plugin_ipscan

Use `ipscan`

List interfaces

Section titled “List interfaces”

The plugin preserves the standalone interface inventory as structured records:

Terminal window
ipscan --list | select name index mac ips is_up is_loopback
ipscan --list | where is_up and not is_loopback

Scan a network

Section titled “Scan a network”
Terminal window
ipscan --network 192.168.1.0/24 --numeric
ipscan --interface eth0 --timeout 5s --retry 2

Each result contains an IPv4 address, MAC address, optional reverse-DNS name, and optional vendor lookup. The summary also reports packets received, filtered ARP packets, and elapsed time.

Filter and export

Section titled “Filter and export”

Because the plugin returns native values, use ordinary Nushell pipelines:

Terminal window
ipscan --network 192.168.1.0/24 --numeric |
  where vendor != '' |
  select ipv4 mac vendor


ipscan --network 192.168.1.0/24 --numeric |
  to json | save hosts.json

The scanner sends Ethernet/ARP frames rather than using the kernel neighbour cache. Run it only on networks you are authorized to inspect, and expect interfaces, VLANs, firewalls, and container capabilities to affect results.
