No idea what you are talking about.
Your ISP issues you an IP address. This is assigned to your "gateway" device, which is typically your cable/DSL modem.

Most home networks then have a router connected to the modem - though in the last couple years, the routers are integrated with the modem in one box.

Note these devices often have yet another network device integrated within, the WAP or wireless access point. 3 separate network devices that just happen to share a circuit board, case and power supply.

Taking it further, most also have a 4-port Ethernet switch too - so they are really 4 in one devices.

If you have just one device, the modem, and it has 4 Ethernet ports on the back, then you have an integrated 4-in-one "gateway device.

If you have a separate modem and a router, then your router is likely a "wireless router" and integrates the router, WAP and 4-port switch in one device. In either case, the router portion issues each of your connected devices unique and new IP addresses which typically start with 192.168.

If you only have a basic modem, it will have one input and one output and you can only connect one computer to your entire network. That would be very rare these days a most home have several devices that connect (multiple computers, cell phones via wireless, networked printers, "smart" TVs and BlueRay players, tablets and more).

My point is, your ISP may have issued you a new IP address that your modem assumed. But your router kept the same 192.168.xxx.xxx addresses to your connected computers. That would not be uncommon.

Clear as mud, huh?
