Connected unknown device with unknown IP
In case of connecting new or old device with unknown configured IP address, there are several possible approaches to get the IP:
- Wireshark and see ARP messages - you can also navigate to Statistics -> Conversations
- Ping address 224.0.0.1 - multicast all node address
- Ping broadcast address 255.255.255.255, but Windows does not support it
In case of connecting device, that do not respond, it may need IP address from DHCP server, then after connecting it to router/DHCP server it will get address and will be able to communicate
Other tool:
IP/MAC on port
- Show MAC table on switch - you get mapping port number <--> MAC address
- Show ARP on router/default gateway
