Activities
edit- Review IP address settings for your local network:
- Windows:
- Review Microsoft: How do I fix network adapter problems? and Microsoft: Change TCP/IP Settings. Review network settings for your system.
- Review ipconfig. Complete the activities to display IP address information, all information, and release and renew a dynamic IP address.
- OS X:
- Review Apple: About Network Utility. Use Network Utility to review network settings for your system.
- Review MacWorld: Configuring Your Mac's Network Settings Use System Preferences / Network to review network settings for your system. Use the Advanced button and TCP/IP settings to renew your DHCP lease.
- Review Wikipedia: ifconfig. Use
ifconfig
to review network settings for your system.
- Linux:
- Review YoLinux: Network GUI Configuration Tools. Use Network Configuration or System Settings / Networking to review network settings for your system.
- Review Wikipedia: ifconfig. Use
ifconfig
to review network settings for your system. Review CyberCiti: Linux Force DHCP Client to Renew IP Address. Usedhclient
to release and renew a dynamic IP address.
- Windows:
- 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.
- Validate your IPv6 knowledge:
- Review Jacob Salmela: Earning IPv6 Certification from Hurricane Electric and the walkthroughs for Newbie and Explorer.
- Visit Hurricane Electric: IPv6 Certifications. Register for free IPv6 certification testing and complete the Newbie and Explorer certifications.
- Practice subnetting:
- Review Understanding IP Addressing: Everything You Ever Wanted To Know and complete the exercises in the appendix.
- Generate practice subnetting questions using this Subnet Calculator.
- Review EasySubnetting.com subnetting resources.
- Play the Cisco Subnet Game.
