IP of a device set to 255.255.255.0, how can I recover?

Hey!

Long story short I had a device get configured to where its static ip is 255.255.255.0. I had concerns that it happened but just had it confirmed via wireshark.

It’s a small Linux computer that I have no way to communicate with outside of across Ethernet. I need to be able to putty in to the device and reconfigure it so that it’s on a normal ip. Is there any way to communicate to a device who’s IP is 255.255.255.0 outside of a console cable?

Thanks.
