Actually, quantumcomm.com is a more interesting traceroute. Especially hops 11 and 12, clearly being passed by Sprintlink. Does anyone besides me see it as an issue that Sprintlink would pass those packets? No, the network 10 isn't in my routing tables.
Should I be filtering all reserved space at my border, or would it be reasonable for me to expect the big guys not to take packets with clearly inappropriate source addresses?
You don't need to see the prefix for 10/8 to be able to pass packets through hosts in said prefix. Some consider it poor form to use RFC1918 space for hosts that are visible to the outside world. As long as you don't _announce_ said space to the rest of the world it really only breaks MTU path discovery and maked debugging a little more difficult.
