What is an IP Address?

An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to the internet. It serves as your device's "postal address" on the internet, allowing other devices to find and communicate with yours.

Public vs Private IP

• Public IP: Visible to the internet (shown above)
• Private IP: Used within your local network
• Static IP: Doesn't change
• Dynamic IP: Changes periodically

Privacy Considerations

• • Your IP can reveal your approximate location
• • Websites can track you using your IP address
• • ISPs can monitor your internet activity
• • Use VPN for enhanced privacy

IPv4 vs IPv6

• IPv4: 32-bit (e.g., 192.168.1.1)
• IPv6: 128-bit (e.g., 2001:db8::1)
• IPv6 provides more available addresses
