What I would like: to determine the current IP of a host (a networked camera to be specific)
What I have: its MAC, its previously documented hostname and IP
What I have done: ping the IP, ping the hostname, check the DHCP leases, check the DNS records, check the ARP table, ping the subnet broadcast then check the ARP table, try the IP in a browser
The short story: This device was previously configured, then an office relocation took it out of the network. I would like to reintegrate it, ideally with its previous configuration intact.
The details: The camera was configured as 10.25.22.37 (or .38), on a /24 subnet, on a particular VLAN. It has a documented hostname. I have access to all the network devices it might feasibly be going through. I have confirmed that it is on the same VLAN as my laptop, and according to the documented configuration, it should be on the same subnet as well.
The problem: I still cannot find any trace of it, other than its MAC showing on the correct port of a managed switch.
Unfortunately, my superiors required a quick resolution and I had to reset it and start from scratch. But thank you all for your helpful suggestions.
