DHCP lease says 192.168.100.245 is enabled and bound when I hit the check status button, but you can see ping says otherwise.
Good thing Normis and friends put the IP ARP table in or I would not have found my DVR at 192.168.100.210.
What’s really weird is this DVR is hard coded to .245 and up until I went to 7.1.2 it was working fine at that IP.
I had to change the DVR client program and verified it’s at .210 by the web interface.
This lease seems to be statically defined. The dynamic leases, created when client initiates DHCP handshake, have letter “D” in second column (between index number, in your output it’s “13”, and address), which posted line doesn’t show.
Static leases will always appear in lease list, even if they’re not actually used at the time. The usage is indicated by value “bound” in “STATUS” column. The line you posted has empty value there which very likely means that client didn’t actually start DHCP handshake.
What I’d do: go to device management interface and verify that it’s network interface is actually set to use DHCP as means of obtaining network settings.
The check button has nothing to do with that… It does not indicate that the host is active or not…
If the status of a lease is busy, then the check status button will free it in case of no response…
Most probably the DVR has a static IP configured and at some point you had enabled the DHCP, so a lease was offered…
