1. Introduction

1.1 What an IP Address Is

A brief explanation of an IP address as a unique identifier assigned to devices on a network, allowing them to communicate with other devices and online services.

1.2 Public vs. Private IP Addresses

• Public IP Address: The outward-facing address visible to the internet.
  
• Private IP Address: The internal address your device uses within a local network (home, office, Wi-Fi).
  

1.3 Why Knowing Your IP Address Matters

• Understanding your network for troubleshooting connectivity issues
  
• Configuring security settings like firewalls or parental controls
  
• Managing devices within a network for setup, monitoring, or diagnostics

2. Understanding IP Address Types

2.1 Public IP Address

Definition:
A public IP address is the unique identifier assigned to your device by your Internet Service Provider (ISP) that is visible to the entire internet.

How it interacts with the internet:

• Allows devices to send and receive data over the internet.
  
• Identifies your network location for web servers, email services, and online applications.
  
• Necessary for activities like hosting a website, gaming, or remote access.

2.2 Private IP Address

Definition:
A private IP address is used within local networks to identify devices internally, such as computers, smartphones, or printers. These addresses are not visible to the wider internet.

How it works inside local networks:

• Enables communication between devices within the same network (e.g., home Wi-Fi or office LAN).
  
• Helps conserve public IP addresses by allowing multiple devices to share a single public IP via a router.
  

The three private IP ranges:

• 10.0.0.0 – 10.255.255.255
  
• 172.16.0.0 – 172.31.255.255
  
• 192.168.0.0 – 192.168.255.255
