In the cases I've seen the roboRIO has the expected
- Hostname: roboRIO-team#-FRC
But with
- DNS Name: roboRIO-team#-FRC.frc-robot.local
I can't edit the DNS name through the web browser and I haven't tried other methods.
On the PC connected to run the Driver Station it might or might not include a DNS Suffix Search List:
frc-robot.local (from an ipconfig /all).
It appears to be somewhat random on any particular PC, i.e., I can have two side-by-side PC's attempting to connect and one will work, but the other fail. After disconnecting/restarting the radio both PCs may work.
Depending on if the PC has the search suffix then the Driver Station will connect, but code download still might fail probably from not including the unexpected DNS suffix.
I made Kevin aware of the issue.
