Where would MAC address capture occur on the network? MACs are local to L2 traffic, so once a frame turns into a packet and is routed, the sMAC of your PC is no longer present in the data. If you're on your home network, this has no impact what so ever.
- paulfurley 9y agoThe capture would occur inside the router. You can just dump its ARP table which translates between MAC and IP address. "If you're on your home network, this has no impact what so ever." Yes, I'm fairly happy with my own tracking policies :D
- rlpb 9y agoActually, this is no longer true. An autoconfigured IPv6 address can leak your MAC address, depending on your settings, as one mechanism for autoconfiguration embeds your MAC address right into your IPv6 address.
- just1nn 9y agoI have Fibre to the Home at 1Gb/sec, but so far, they do not support IPv6. That's something interesting for me to look into though, so thank you. I was providing ADS-B flight data to a website, and then I realized that they were posting my MAC, my NAT'd IP, and my GPS location to the world. That L7 will get ya every time.
