The first hop is your router, both 192.168.x.x and 10.x.x.x address space are reserved for internal network addresses.

  • yeah I know, I am asking about 10.37.242.185 10.37.242.173 10.37.241.17 – kifcaliph Jan 13 '15 at 21:17

    a 10.x.x.x address IS NOT routable on an IP level. The address has to be local to your network. Perhaps your modem acting as a second NAT device on the way to your ISP? – Maumee River Jan 13 '15 at 21:23
  • @MaumeeRiver 10.x.x.x is routable at an IP level, just not publicly routable. It is a reserved private address block. Did you mean "not routable on an ISP level"? – schroeder Jan 13 '15 at 23:50
