I mean the host that receives the packet. Weren't you suggesting to use 127/8 as an alternative to link-local addresses?

No, I was saying that you can assign different loopback addresses to different interfaces even if the interfaces have been assigned the same routable IP address. This lets you distinguish them.

On my Mac, however, loopback addresses are only assigned to the `lo0` interface, not to physical interfaces. I don’t know anything about how other platforms handle it, so I caveated my explanation with “maybe nobody does this in practice.”
