There are three ways that people protect their IP addresses, which include: Through a VPN service, which is considered the fastest and most secure out of any other option. Through an IP-protector browser like Tor or Brave. With the help of a Proxy server, which might be a little bit risky considering it uses another user's network to mask your IP.
Therefore, the best way is to find a reliable VPN service provider and use it on your devices like Router, PC, Laptop, Phones, Smart TVs, etc.
