The main ways one can change their IP address at home are the following:
Please remember that unplugging or turning off the router will kick out everybody connected to the internet in your household. Keep that in mind in case you are sharing the connection with others. Moreover, the success of the method above depends on the way your internet service provider allocates and leases IP addresses to users. Sometimes, after reconnecting the ISP may give you the same IP address
The instructions above apply to users that are using Dynamic IP addresses (the majority of home users). If you are using a static IP address which is usually something you would have done consciously, as it is usually more expensive, the method above will not work.
There are multiple commercial and free VPN providers that one can use to connect to the internet. Generally a commercial VPN provider is preferred against a free one, as commercial providers are usually faster and more secure. Moreover, commercial VPN providers offer multiple servers in multiple geographical locations and one can user any of the available servers to change their IP.
