🧩 What is an IP Address?
An IP address (Internet Protocol address) is a unique string of numbers separated by periods or colons that identifies each computer using the Internet Protocol to communicate over a network. It acts like your device’s home address on the internet, allowing data to find its way to and from your device.
🗂️ Types of IP Addresses
- Public IP Address: Assigned by your Internet Service Provider (ISP) and used to identify your device on the wider internet. This is the address websites and online services see.
- Private IP Address: Used within your local network (like your home Wi-Fi) to identify devices to each other. Not visible to the wider internet.
- Static IP Address: An IP address that doesn’t change. Often used for servers or important devices.
- Dynamic IP Address: Changes from time to time, usually assigned automatically by your ISP or router.
- IPv4 and IPv6: IPv4 is the older, more common format (e.g., 192.168.1.1), while IPv6 is newer and supports more devices (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
⚙️ Applications of IP Addresses
- Enabling devices to communicate over the internet and local networks
- Accessing websites, apps, and online services
- Remote work, gaming, and video conferencing
- Network troubleshooting and device management
- Location-based services and content delivery

🛡️ IP Address and Network Security
- Firewall Protection: Firewalls use IP addresses to allow or block traffic, protecting your devices from unauthorized access.
- VPNs and Proxies: These tools mask your real IP address, helping to keep your online activity private and secure.
