I think "c-73-189-65-18.hsd1.ca.comcast.net" is their naming system for end modems, not internal infrastructure, but don't quote me. When I look up the names of routers in the traceroute I don't think I see that type of name, but it may be that's an irresponsible poorly verified comment on my part.
For example from traceroute to Michael: 186.78.151.162.in-addr.arpa domain name pointer po-1-rur101.pinole.ca.sfba.comcast.net.
ooooooooooooooh, omigosh - I just perfected a traceroute to Michael, entirely within the CC network:
traceroute to 96.86.170.229 (96.86.170.229), 30 hops max, 60 byte packets 1 50.242.105.62 2.080 ms 2.743 ms 3.439 ms 2 10.61.209.66 14.028 ms 10.61.209.67 13.729 ms 10.61.209.66 14.373 ms 3 96.216.9.141 12.757 ms 96.216.9.137 13.045 ms 96.216.9.141 13.401 ms 4 68.85.154.113 21.023 ms 68.85.154.117 21.093 ms 68.85.154.113 20.944 ms 5 96.108.99.249 26.011 ms 25.722 ms 26.272 ms 6 68.86.143.89 23.688 ms 68.86.143.93 21.156 ms 20.778 ms 7 162.151.86.58 22.077 ms 20.330 ms 162.151.87.226 20.215 ms 8 162.151.79.134 21.787 ms 162.151.78.186 17.686 ms 162.151.79.134 21.466 ms 9 68.85.103.154 19.388 ms 68.85.191.206 12.456 ms 68.85.103.154 14.255 ms 10 73.189.65.18 21.185 ms 36.832 ms 31.356 ms 11 96.86.170.229 36.366 ms 34.933 ms 34.918 ms root@routr0:/z/r/srv#
It appears that 73.thing is in fact Michael's upstream router.
Ok, did everyone else already know that? Am I late to the party?
