    IP Address Basics

    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.

    IPv4 vs IPv6

    IPv4

    Format: 192.168.1.1

    32-bit addresses, about 4.3 billion possible addresses

    IPv6

    Format: 2001:db8::1

    128-bit addresses, virtually unlimited addresses

    Public vs Private IP

    • • Public IP: Visible to the internet, assigned by your ISP
    • • Private IP: Used within your local network (192.168.x.x, 10.x.x.x)
    • • Static IP: Doesn't change, often used for servers
    • • Dynamic IP: Changes periodically, common for home users
