Activities[edit]

  1. Review IP address settings for your local network:
  2. Identify public IP address information:
    • Perform an Internet search for "what's my ip". Use an available website to determine your public IP address.
    • Use a Regional Internet Registry to search the Whois database for IP address information.
    • Perform an Internet search for "ip location". Use an available website to determine the location of your public IP address.
  3. Validate your IPv6 knowledge:
  4. Practice subnetting:
