I've setup an FPGA to recieve ethernet packets and look at the IP address of the sender, if it matches my PC, increase a display counter.

I only see the counter increase when I send broadcast messages, for example, ping 191.9.255.255 from my pc 191.9.50.7 mask 255.255.0.0

If I try to ping an unused IP address on the network, the request never reaches my FPGA, the network switch doesn't try to send it there.

Any idea how I can resolve this?

Seems I am getting ARP requests at the FPGA from my ping, didn't see it because the target IP address occupies a different part of the packet for ARP requests....
so now I have to implement ARP before I get anything else done.

or you use the arp command on your pc to make a static arp entry

Well, I'm only just figuring out how everything fits together, so I didn't think of that.
Still, it needs to be implemented anyway so it's no huge loss. Bit of a pain that I've "tidied up the code" and it no longer works
