NESS D8XD deault ip address confusion

Recommended Posts

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://nesscorporation.com/ness-security/ness-control-panels/home-security/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

did you check the router table after the ping and before the restart?

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

Good point Pachy,,,,I totally forget about this command

Would be used from any PC on the network ?

Peachy

 

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?
