Gateway IP

hello friends

Can any one tell me how to find the GATEWAY IP of PC connected to my network.

I have three different gateway routers, and we will assign gateway depending on the bandwidth utilization.

I am able to find the computer name, workgroup, ip address, and username, MAC address of workstations from my PC using Angry IP Scanner, but not able to find which GATEWAY IP assigned to which PC and what are the DNS values.

Please provide some HELP. Please post your reply soon…..
