- denton-scratch 3y agoYeah, but I think that WP page is wrong. It relies on the page Reserved_IP_addresses, implying that a martian is a packet with a source address within certain ranges. In fact a martian is a packet with a source address for which the receiving interface isn't configured; any address could be a martian, depending on how the interface is set up. Hey, if I'm wrong, please set me straight.
- benou 3y agoLooking at RFC1812, Martian packets [1] seems to be reserved addresses only. What you're talking about is referred to as source address validation [2] also known as strict reverse path forwarding (RPF) [3].
