Discover IP devices

Hello!

I need to periodically update devices attached to an IP network according to their MAC address.

What is the best way to discover devices and their IP and MAC addresses?

I do not have access to the dhcp.releases file.

Thank you very much,
Murdock

Check out arp-scan

you could creating a shell script (use for loops) that uses the command arping (iputils-arping). you'll get a line with this as output:

Code:

Unicast reply from 192.168.0.55 [00:14:C1:0F:54:5A]  0.585ms

the code in the for loop should be about this, assuming you use 3 loops:

Code:

arping -w 1 -c 1 10.$x.$y.$z
