The mDNS address for both the Ethernet and USB network connections to the roboRIO is:
Using this address allows the network to automatically connect to whichever wire you happen to have plugged in-USB or Ethernet. It also automatically recovers and switches paths if one of the cables becomes unplugged, but the other is still available.
The fixed static IP address for the roboRIO via
just the USB port is:
It will stop working when the USB cable is disconnected. So this won't work via the Ethernet port, e.g., wirelessly.
The roboRIO Ethernet port IP is dynamically assigned by DHCP and can change based on what other IP devices are also requesting DHCP assigned address.
So it doesn't have a fixed IP address from session to session, so don't depend on the IP currently assigned. It may change the next time you boot and have added an IP camera or have a programming laptop connect before the roboRIO does.
