Question Answer Session on Subnetting - CCNA | Network Zeal
VLSM (Variable Length Subnet Masking)
VLSM allows for subnets of different sizes to be created from a single network. This is useful for efficiently utilizing IP addresses.
- *Benefits:* Efficient use of IP addresses, allows for more hierarchical IP addressing.
- *Example:* If you have a network of 192.168.1.0/24 and need subnets for 100, 50, and 25 hosts, you can divide it into smaller subnets using VLSM.
FLSM (Fixed Length Subnet Masking)
In FLSM, all subnets are of equal size. This method is simpler but can lead to IP address wastage.
- *Benefits:* Simplicity in design and management.
- *Example:* If you have a network of 192.168.1.0/24 and want to create 4 subnets, each subnet will be of equal size, say 192.168.1.0/26, 192.168.1.64/26, etc.
Subnetting
Subnetting is the process of dividing a network into smaller networks (subnets).
- *Purpose:* Improve network performance and security, efficient IP address usage.
- *Basic Steps:*
1. Determine the number of required subnets and hosts.
2. Calculate the subnet mask.
3. Divide the network accordingly.
4. Assign IP addresses to each subnet.
#### Example:
Let's say you have the network 192.168.1.0/24 and want to create 4 subnets.
1. *Determine the number of subnets:* 4 subnets require 2 additional bits (2^2 = 4).
2. *Calculate the new subnet mask:* Original mask is /24, adding 2 bits gives /26.
3. *Divide the network:*
- 192.168.1.0/26
- 192.168.1.64/26
- 192.168.1.128/26
- 192.168.1.192/26
4. *Assign IP addresses:* Each subnet has 64 addresses, but 2 are reserved (network address and broadcast address).
