Well, that's some machine that's on the same subnet, as far as IP is
concerned.
Is it your machine?
What does the routing table look like on your machine?

Well, it's apparently trying to go through *some* machine.
Unfortunately, that machine can't get to 24.127.52.15 - 24.127.52.10 is
returning a Host Unreachable.

OK, so I infer from "from 24.127.52.10" that 24.127.52.10 is your
machine.
The question is whether it has something in its routing table to tell it
that it's its own router to some machines (machines it can't, in fact,
get to).
