Linux Networking

I have 4 VMs running on redhat. Currently two of them are up and running.

I have 4 virtual NICs on each VMs. I configured one NIC to the following IP.

172.16.3.1

when I tried to bring this interface up it says,

Error, some other host already uses address 172.16.3.1

How do I find out which host is using?

I tried to ping the IP and its pinging. when i tried to do arp -a, i don't see this address.

Is it an IP on the local subnet? Then you could check the routers arp-table to see if the IP's used and to which mac-address.
