Question 1

What is my IP address?

Accepted Answer

Your IP (Internet Protocol) address is a unique identifier assigned to your device when connected to the internet. It is like a postal address for data packets — it tells servers where to send responses back.

Question 2

What is the difference between IPv4 and IPv6?

Accepted Answer

IPv4 uses 32-bit addresses (e.g., 192.168.1.1) and supports about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:db8::1) and provides a vastly larger address space to accommodate the growing number of internet-connected devices.

Question 3

What is a public vs private IP?

Accepted Answer

A public IP is visible to the outside internet and is assigned by your ISP. A private IP (like 192.168.x.x or 10.x.x.x) is used within your local network and is not directly accessible from the internet.
