A public IP address is the address assigned to your internet connection. Websites use it to communicate with your device over the internet.
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses and supports a much larger address space.
A public IP address is assigned by your ISP and identifies your connection on the internet.
No. Your public IP is visible to websites you visit, but it does not directly reveal your identity.
Most ISPs assign dynamic IPs, which can change when you reconnect or over time.
