@christianh10 - I don't have a garden? Must be somebody elses house!

So If i had for example 192.168.1.23 /27 255.255.255.224 Subnets = 8 192.168.1.0 192.168.1.32 192.168.1.64 192.168.1.96 192.168.1.128 192.168.1.160 192.168.1.192 192.168.1.224 So each router could have the subnet and each range of subnet a number of 30 hosts for each router?

I thought this video was excellent, for people that don't understand. It doesn't get much easier than this, read a section on subnetting from a sybex book and this video will make sense.

@Dark0Temptation there is a formula: 2^n (where n is # of 1s in the host portion when converted to binary); in the example: there are 2 1s in the host portion (255.255.255.192): 192 is the host portion so what is 192 in binary? 11000000; therefore use the formula: 2^n; and n = 2; so 2^2 = 4 so 4 subnets

Now getting to the video: he just told us all how to make a subnet chart to make it much easier to subnet.

he used the 0 subnet: 192.168.1.0 (no host can be here); and then he added the block # (which in this case was 64 to each the 0 subnet: again no host can be here).

He tells you how to get the broadcast / first host range / last host range: the last octet he is talking about is the 0 subnet;

I hope this explains some things...

@roybunch76 He took /26 as an example and said how to make a subnet chart. Instead of using the cheat sheet he used, maybe it would've been easier to tell the formulas? So here goes:

Block Size=256-b (where b is the subnet host #) ex: 255.255.255.192 (b = 192); so block size:256-192=64

# of subnets=2^n(where n is the number of 1s in binary in the host portion); 255 is 8 1s in binary; how much is 192? 192 is 2 1s:110000000 = 192; so 2^2 = 4; that is why there are 4 subnets
