| Do any of you know an easy way of subnetting? | |

| Can you expand on that question perhaps? | |
|
| the easiest way is to learn it

without knowing why and how, any trick/short cut only serve the immediate purpose of getting it done, without understanding what it is you are actually doing.
goes wihtout saying... if you know it, it is easy... | |

| Read Sybex CCNA Study guide (Todd Lammle). The chapter on subnetting will teach you to subnet in your head. And it really works! | |
|
| Todd Lammle's CCNA Study Guide should fix you up. I wish the test (CCNA) consisted of 60 subnetting questions. Two things that helped me out when I was learning to subnet: try converting your octets into bits before hand and do as many practice questions as you can find until you know it cold. It isn't much to it so don't be overwhelmed at first. | |

| I found knowing the power of 2 in your head worked well. Counting from right to left. For example if you want to know how many subnets and hosts etc seeing the number of one for subnets. say 240 subnet is four ones so I count 2 4 8 16 minus two gives me 14 subnets. Also remember beyond the eight octets with power of 2, this helps with subnetting class B. SO to the power of 9 is
2(1) 4(2) 8(3) 16(4) 32(5) 64(6) 128(7) 256(8) 1024(9)
At first you'll think it's impossible to subnet in your head but practise practise practise and you'll get it. Sorry if the above is confusing, different methods work for different people... |
