Can I send a message to someone on the same network?

[cybrscot]

If I'm on a wireless network can I send a message that will pop up for the target computer?

I can find the IP addresses of other computers on the same wireless network that I'm on, with IP Scanner.

Once I have the IP address, can I somehow send a message directly to that IP address?

Thanks

Not if the target computer isn't running some sort of messaging app, and then you'd have to know their messaging login, not their IP address. You can't send a message to any computer with only their IP address.
