In this article we cover one of what I have found to be the most common stumbling blocks for individuals attempting to pass the CCNA. This comes from experience in helping several individuals through ...

The way you combine the /24 subnets is to change the subnet mask to a /22. (ie. 255.255.252.0) This makes it all one contiguous address space. Just change the subnet mask to 255.255.252.0 and ...

I feel stupid asking this, but I have always had a hard time understanding subnets no matter how much I have read on them. I always end up more confused than when I started.<BR><BR>What I do ...
