Actually yes. At first I had the same thought that you did, but
knowing which router the packet was supposed to have come from makes
it easy to tell from the output of a traceroute weather the routing
changed in the middle. Having to use IP addresses to figure this out
is much more work. On the other hand, I do question the idea of
trying to cram all this info into the the interface names in the DNS.
