Just a quick question that kept puzzling me is that since ISPs use DHCP, what’s stopping me from setting up a static IP on my routers WAN interface disabling DHCP. Is there a way to ensure that a customer does not do this or is it just trust between the customer and ISP. When running a trace route to a IP address on the same subnet there is only one hop through the CMTS before the destination. Can CMTS’s regulate IP Addresses in this way or is something else implemented.
may be a stupid question but I am just curious
