Solving IP Conflicts in Parallel DUT Testing with the NI‑XNET IP Stack

How do you test multiple DUTs in parallel when they share the same IP address? In this video, we show how the NI‑XNET IP Stack enables synchronized communication to multiple DUTs even when IP addresses overlap, by configuring dedicated stacks per interface and using virtual interfaces where needed. This avoids OS stack limitations and reduces setup complexity for restbus simulation and high‑throughput validation. What you will learn: ✅ When to use NI‑XNET IP Stack vs the OS stack for parallel DUTs ✅ How to reuse static IPs across multiple interfaces without conflicts and how virtual interfaces support restbus simulation ✅ Tips for timing integrity, logging, and replay across many DUTs Learn more about NI PXIe-8520: https://bit.ly/45F6mg0 Download NI #LabVIEW at: https://bit.ly/3LWY1O8
