Ip Subnetting From Zero To Guru Pdf !full!
I can’t directly provide or link to a PDF file. However, here’s what you can do to find "IP Subnetting from Zero to Guru" (or a similarly titled guide):
2.3 Network Address, Broadcast Address, First/Last Host
- Network address = all host bits = 0
- Broadcast = all host bits = 1
- Valid host range = (network +1) to (broadcast –1)
To be a guru, you must memorize the "Magic Row" of binary values:128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 ip subnetting from zero to guru pdf
When you need to carve up a network, use these two formulas: Number of Subnets: 2 to the n-th power is the number of bits borrowed from the host portion). Number of Hosts per Subnet: is the remaining host bits). One address is the Network ID , and one is the Broadcast Address . You can't give these to computers. Phase 4: The "Magic Number" Shortcut (The Guru) Forget complex long-form math. Use the Magic Number method to find your boundaries instantly. Example: Subnet 192.168.1.0/26 Find the Mask: A /26 means 24 bits (255.255.255) + 2 more bits. Calculate the Last Octet: The first two bits are 128 and 64. 255.255.255.192 Find the Magic Number: Subtract the interesting octet from 256. Count by the Magic Number: Your networks start at: Define the Range: For the first subnet (.0): Network ID: 192.168.1.0 First Host: 192.168.1.1 Last Host: 192.168.1.62 Broadcast: 192.168.1.63 (one less than the next network) Phase 5: VLSM (The Master) Variable Length Subnet Masking (VLSM) I can’t directly provide or link to a PDF file
Determine the Magic Number: Subtract the interesting octet from 256. If your mask is 255.255.255.224, then 256 - 224 = 32. Your networks will go up in increments of 32. Chart the Networks: Network 1: .0 Network 2: .32 Network 3: .64 ...and so on. Variable Length Subnet Masking (VLSM) Network address = all host bits = 0
