P/Net address� it did not change. Internet Protocal(TCP/IP) Properties did not change. When the network is physically disconnected, my VI after several runs returns 127.0.0.1. So, how do I get my IP address whether it�s connected to the network or not?If you're getting a dynamically assigned IP address from the network, then String to IP will return that IP but it may not be constant. See if TCP/IP properties are set to "Obtain an IP address automatically". If you disconnect from the network, then the IP address will default to something and I wouldn't be surprised if the default is 127.0.0.1. If you want to always have the same IP, then the ICP/IP properties should be changed to use a fixed IP but you'll certainly need to check with your IS department before doing so.
