Multiple Choice Questions on IP Addresses: High School Computer Science

📚 Quick Study Guide

• 🌐 Definition: An IP address (Internet Protocol address) is a numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.
• 🔢 IPv4: Uses a 32-bit address space, represented in dotted decimal notation (e.g., 192.168.1.1).
• 🧅 IPv6: Uses a 128-bit address space, represented in hexadecimal notation (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
• 🔑 Classes: IPv4 addresses are divided into classes (A, B, C, D, E) based on the first octet, determining the network size and host addresses.
• 📡 Subnet Mask: Used to divide an IP address into network and host addresses. (e.g., 255.255.255.0)
• 📝 Private IP Addresses: These are IP addresses reserved for internal networks and are not routable on the public internet. Examples include:
  • 10.0.0.0 – 10.255.255.255
  • 172.16.0.0 – 172.31.255.255
  • 192.168.0.0 – 192.168.255.255
