Dear folks

NESS D8XD alarm system installed on a business for my friend and a technician who installed it he said he didn't change the alarm system default ip address.

http://nesscorporati...ity/k-6308.html

Default ip is 192.168.0.251 ,,,as per the advise of their National Customer Service Centre,,,I called them and spoke with them

The confusing part I can ping this ip address (192.168.0.251) but it is neither in the list of the attached wired devices nor in the list of attached wireless devices (any way NESS is a wired box)

Snapshot below is for the attached wired devices

Confusion how can I ping the ip address and it is not listed in my router table ???

Thanks

did you check the router table after the ping and before the restart?
Of all tyrannies, a tyranny sincerely exercised for the good of its victims may be the most oppressive. It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. ~C. S. Lewis

Run the command arp -a and match the MAC address to the physical device; the only way to visually confirm.

Please have a look at the result below

Ping from a PC within the same network didn't show static ip addresses for printer and alarm control system within ARP table

Then I did ping both addresses 192.168.0.200 (printer) and 192.168.0.251 (Alarm system) as a result both of them shown in ARP table,,,,,means when there is activity (traffic) then it would be shown in ARP table!!!

Second issue both ip addresses 192.168.0.200 (printer) and 192.168.0.251 (Alarm system) shown as dynamic not static why ???

Is it true that the printer and alarm system have those MAC addresses then? Not sure why they are what I see there. Have you checked the DHCP leases on the DHCP server to see if it handed out those IPs to those MAC addresses?
