all that information is visible to everyone who knows how to read it,DHCP on the router you "hacked" would give you an address, your MAC address maybe logged against that ip depending on the hardware/software, but it is not a ISP address it is internal to the home network like a non-routable 192.168.x.x range, therefore virtually impossible to trace.
