Re: HOWTO: Understand Binary and Subnetting
by Jesse on Monday October 27, @07:32PM

Hi there, Iam just wondering why in a class C network the first and last subnets are not used. Making only six subnets, even though there are 8. In your article you say that you cant count all 1s or all 0s. So are you really saying that these whole subnets are usless because you cant supply a network address for the first subnet and you cant supply a broadcast address for the last subnet? Am i on the right track. ? It seems like a huge waste of address space. Is there a way that you can use this 2 subnets? I have heard that this may be possible through super subnetting. Am i on the track ? Great article by the way, helped heaps. Thanks Jesse
