[BUG] Missing IP address

[mmattel]

When configuring NS for the range (10.x.y.0/24), I get a list of addresses found, but this list is not complete.
The last address shown is .231 but .230 is not shown though present.

When running nmap from the console manually in the HA container same as called by NS:
nmap 10.x.y.0/24 -sn | grep 10\.
I get as result ... .231, and .230 as last address.

Note that in the above list .231 is printed before .230 !

This means that NS does not provide all addresses found.

The culprit can be, that the last address found has a lower number than the highest IP in the list.

As I got curious...
I wrote a small script that runs in the PI that runs HA but not inside HA and uses the same mechanism as NS except async.
The script ran directly after I restarted NS, means that the values should be identical...

The results are unreliable, because they change from time to time.

Maybe another mechanism should be considered querying the data...

import nmap

nm = nmap.PortScanner()
nm.scan(hosts="10.x.y.0/24", arguments='-sn')

devices = []

for host in nm.all_hosts():
  ip = nm[host]['addresses']['ipv4']
  devices.append({
    "ip": ip,
  })

devices.sort(key=lambda x: [int(num) for num in x['ip'].split('.')])

print(*devices,sep='\n')
