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:

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?
