Pop Quiz: Windows ipconfig command

Do you know how to quickly release and renew DCHP leases on Windows PCs? Test your knowledge of the Windows ipconfig command.

When troubleshooting network connection issues on a Windows PCs, IT pros often turn to the venerable ipconfig command. This tool can be one of the quickest ways to diagnose and resolve connection problems related to TCP/IP.

Sure, you can perform the same troubleshooting tasks from the Windows GUI. But why dig through multiple menus, when you can type a few characters into a command prompt? So, I've put together this short quiz to test your knowledge of the Windows ipconfig command. I'm using Windows 7 as the basis for this quiz.

Note: Unfortunately, our poll tool, which I use to create each pop quiz, doesn't let me indicate a correct answer after each question. To keep from giving away the answers before everyone has a chance to test his/her knowledge, and ruining all the fun, I've published the answers on the second page of this blog post. I encourage everyone to answer all the questions before looking at the second page or using your favorite search engine to find the answers.

Answers are on the next page.

I didn't give up when I didn't know I just threw a dart at the screen..(crash and burn) oops not a good idea. I missed 3 -> renew6, release6, and showclassid (I picked displayclassid) Good to know this stuff even if I don't use it very often.

Any network trouble on a PC or server and I'm instantly at the cmd line using ipconfig. I was unaware of the IPv6 switches. I work primarily with XP and Server 2003 in a SMB and the IPv6 switches don't show up with /? with the included versions of ipconfig. With IPv6 just around the corner these will come in handy. Thanks for the quiz.

Who needs all these stupid Windoze commands...Linux just works.

Because I don't "do" networking on Windows... I forgot =) I only use Linux and commands are a bit different - cmd in windows is not really a terminal anyway.. so I just use the GUI. Nice Pop-Quizz nonetheless!

Missed one of the IPv6 questions though... You mentioned the pole tool you use. What is the name of it specifically? (if you don't mind:)

I didn't do too bad, for a nurse! (I missed the last one.) When I'm not fixing people, I'm fixing some-"thing". At home, I am the "IT Specialist". I recently had to use these commands to get my hubby's laptop back online, because when I called Qwest tech support, the guy told me it was "out of his range of expertise". So I had to figure it out myself, and I don't quit until I do! Thanks for the fun quiz and confidence builder.

I think every IT Admin should know these cmd. If they don't then I think they have to start again the basics.

It's a command that we rarely use, but need desperately when we do!

I think I'm getting my old Cisco OS commands mixed up with ipconfig. :(

And I aced it, too. But then I cheated on a couple. '/?' is a wonderful switch...

I think anyone who monitors/manages an AD network would find almost every of those commands useful at one point or another. They'r what i'lld call the basic windows network troubleshooting commands.

This couldn't come at a better time as I am in the process of bringing up a new router. I've always had a preference for the command line as that was the way I was brought up. :)

It's really funny that except for the last question (actually, maybe the last question too) my answer was the majority one...and frequently wrong (didn't know you could get basic info with no switches!). Last question had no clear majority - I got it right, but it was a guess.

I don't normally use all of these commands. We don't even have ip6 yet. But it's nice to stretch the braincells or review my wetware knowledge base.

In XP, you would press Win+R on your keyboard, then type "cmd" and press enter. In Win 7, open the Start Menu, then type 'cmd' and press enter. Once that window is open, you can type 'ipconfig' and get the information.

Linux is basakwards If I wanna go in reverse I use linux if I want to go forwards I use Windows. It's all good though, as long as I get where I want to be. The hard part is when I need to park my life. Having to switch back and forth to get close to the edge.

Your second to last sentence says it all. If only more people had your determination. Put the Qwest "tech" to shame.

I feel sorry for anybody that has to put up with them!
