Wendell's CCENT Skills Blog

IPv6 was formerly in the ICND2 side of #CCNA, but now it’s in the ICND1/#CCENT side. ICND1 includes more than a few IPv6 topics, but the first and often most intimidating topic is the most basic feature: IPv6 addressing. Today’s post introduces the topic, with question and answer posts to follow.

Today’s post shows the solution to subnet design exercise 4, specifically the IP subnets. This post isn’t all that meaningful without reading the other one first – after that, and after you take a crack at creating the design yourself, dive in! Here are some useful links: The original problem statement for this problem The [...]

The subnet design exercises require that you do some subnetting math, but rather than reacting like you would in a help desk or support job role, you plan as if you were in the role of a lead network engineer. If you have seen the other subnet design exercises, you already know the drill. If [...]

Last post, I suggested doing part 1 of a lab in the CCNA Skills blog as a CCENT-level subnet design lab. If WordPress mechanics cooperated, that solution should be posted. Check out the details of the answer in that post. However, because I did tell you to create configurations, and for the CCENT side of [...]

I wasn’t going to do another one of these so soon, and well… in the CCNA Skills blog side of things, I happened to have just written a lab. When I wrote up the answers to part 1 of that lab, I realized that it was a subnetting design review with config. Then I realized [...]

Today’s post shows the solution to subnet design exercise 2, specifically the IP subnets. This post isn’t all that meaningful without reading the other one first – after that, and after you take a crack at creating the design yourself, dive in!

Today’s exercise requires a little more thought than most of my exercise posts. In this case, you’ll start with two class B networks: 172.16.20.0 and 172.16.30.0. The problem also lists a set of requirements. Your job: to come up with an IP subnetting design. You choose the one mask to use in each network, find [...]

Today’s post picks up the discussion of the solution to the subnet design exercise I posted a while back. Start with the post for the original problem statement, and read from there!

Today’s post shows the beginning of a solution to the subnet design exercise I posted last week. This post isn’t all that meaningful without reading the other one first – after that, and after you take a crack at it of course, dive in!

For the US holiday weekend, I thought I’d leave you with a design exercise that requires a little more thought than most of my exercise posts. In this case, you’ll start with a class B network, and a set of requirements. Your job: to come up with an IP subnetting design. You choose the mask, [...]
