zillah Posted November 23, 2018 Share Posted November 23, 2018 (edited) 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 https://imgur.com/a/GPvm98R C:\WINDOWS\System32>ping 192.168.0.251Pinging 192.168.0.251 with 32 bytes of data:Reply from 192.168.0.251: bytes=32 time=6ms TTL=64Reply from 192.168.0.251: bytes=32 time=2ms TTL=64Reply from 192.168.0.251: bytes=32 time=3ms TTL=64Reply from 192.168.0.251: bytes=32 time=4ms TTL=64Ping statistics for 192.168.0.251: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Approximate round trip times in milli-seconds:Minimum = 2ms, Maximum = 6ms, Average = 3ms[/Code] Confusion how can I ping the ip address and it is not listed in my router table ???

crp Posted November 23, 2018 Share Posted November 23, 2018 did you check the router table after the ping and before the restart? 1 Quote Link to comment Share on other sites More sharing options...
Peachy Posted November 27, 2018 Share Posted November 27, 2018 Run the command arp -a and match the MAC address to the physical device; the only way to visually confirm. Quote Link to comment Share on other sites More sharing options...

zillah Posted November 30, 2018 Author Share Posted November 30, 2018 (edited) 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 ???

Peachy Posted December 4, 2018 Share Posted December 4, 2018 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? Quote Link to comment Share on other sites More sharing options...
zillah Posted December 4, 2018 Author Share Posted December 4, 2018 Peachy DHCP range from 205-249 as per attached snapshoot https://imgur.com/a/Bungfwf Have you checked the DHCP leases on the DHCP server to see if it handed out those IPs to those MAC addresses? Yes it does as per attached snapshoot https://imgur.com/a/KlEV9P6 Quote Link to comment Share on other sites More sharing options...
