Your public IP is assigned by your ISP and is visible to websites you visit. It identifies your connection on the internet. All devices in your home share the same public IP.
Your private IP is assigned by your router via DHCP and is only visible within your local network. Websites cannot see your private IP.
Your public IP address is assigned by your Internet Service Provider and identifies your connection on the internet. Every device in your home network shares the same public IP. From your IP address, websites can determine your approximate location (country and city) and your ISP – but not your name or exact address. To protect your privacy online, a VPN replaces your real IP with the VPN server's IP address.
