Real World Subentting Part 1
Hi Let me teach how to subnet in seconds for real. Subnetting with host requirements. Sample 1: Required Host per subnet - 30 address - 192.168.1.0 Step 1. Create the bin table 128 192 224 240 248 252 254 255 128 64 32 16 8 4 2 1 Step 2. Convert the host requirement to binary and count how many bits which means how many 1's and 0's 30 = 11100 = 5 bits(or three 1's plus two 0's) Step 3. Identify the class of address that is given in this case its class c (192.168.1.0) Step 4. Use this formula to get your actual netmask [24 + (8 - Number of bits)] = netmask note: for class c only 24 + (8-5) = 27 From the original netmask of /24 you have now /27 which is 255.255.255.224 Step 5. Find your increment To get the increment simply refer your actual netmask to the bin table. Remember you only need to refer the last octet which .224 because you are subnetting using class c private ad...
