Like 192.168.1.1 it is a private address that exists independently on every network that uses it. Open http://192.168.0.1 while connected to the router's Wi-Fi or Ethernet to reach the admin interface.
If your router uses 192.168.0.1, its DHCP pool is normally 192.168.0.100–199 or 192.168.0.2–254. Changing the LAN subnet is one way to avoid conflicts when connecting two routers or a VPN that uses the same range.
