2.2 Target System IP Address

Given a working network card, the next step is to check which IP address the target system is using inside the simulated network. This would normally be provided over DHCP from a Simics Service Node - it defaults to the 10.10.0.x range on the QSP-x86, but it varies from target to target.

To check the IP address, start a CMD on the target and use the command ipconfig:

C:\Windows\System32>ipconfig.exe

In addition, you need to know the IP address of the service node that works as the default gateway - which ipconfig also returns. To double-check, also run the info command on the service node in Simics:

running> service_node_cmp0.sn.info
