Is this normal or is there a problem with my probe? I've never really taken this close of a look before, I'm unsure if it has an issue or if this is normal.
Do you see any ARP request coming from the probe? It seems that the probe cannot reach it's default router on IPv4.
Yes, it responds sometimes on v4, and always on v6. I'm at a loss to understand it. v4:
