- What is an IP address?
- An IP address, or Internet Protocol address, is a unique identifier assigned to each device connected to the internet. It's like a home address for your computer, allowing it to communicate with other devices over the internet.
- What's the difference between IPv4 and IPv6?
- IPv4 is the original internet addressing system that uses a 32-bit format (like 192.168.1.1). IPv6 is the newer standard with a 128-bit format (like 2001:db8::1) that provides many more addresses. IPv6 was developed because we're running out of IPv4 addresses due to the growing number of internet-connected devices.
- Why don't I see an IPv6 address?
- If no IPv6 address is displayed, your internet service provider (ISP) or network might not support IPv6 yet. Many ISPs are still in the process of transitioning from IPv4 to IPv6. Your router or device settings might also need to be updated to enable IPv6 connectivity.
- Why does my IP address change?
- Your IP address may change because most home networks use dynamic IP addresses, which are assigned by your internet service provider and can change over time. Some networks use static IP addresses, which do not change.
- Is my IP address visible to websites I visit?
- Yes, when you visit a website, your IP address is visible to that site. It's used for network communication and can provide information like your general geographical location. However, it does not disclose personal information like your name.
- Do I need both IPv4 and IPv6 addresses?
- Currently, most of the internet supports both standards in what's called "dual-stack" mode. While having both provides the best connectivity, you can still access most websites with just IPv4. However, as IPv4 addresses become scarcer, having IPv6 connectivity will become increasingly important.
