you might know the definition of VLSM as well as the procedure of implementing VLSM.
Whats more, it’s possible for you to also know the differences between VLSM and FLSM.

What Is VLSM
What is VLSM?
VLSM is the abbreviation of the Variable Length Subnet Mask.
It can be used to increase the availability of subnets because of their variable size.

It is also defined as the subnetting process of subnetting.
Here are four methods in this post.
This subnetting can more efficiently use a given IP address range.

The Procedure of Implementing VLSM
The following is the procedure of implementing VLSM.
If the administrators IP is 192.168.1.0/24, you could follow the steps below to assign a department-level IP.
Step 2: Sort all segments in descending order according to the required block size from highest to lowest.

Step 4: The next data pipe segment needs an IP to handle 50 hosts.
This part provides information on VLSM vs FLSM.
FLSM refers to a strategy where every one of your networks within your infrastructure is the same size.
If you are interested in this part, you’re free to keep going.
In FLSM, all subnets have the same size and the same number of hosts.
Therefore, by allowing the routing systems, IP address addressing efficiency is higher.
In FLSM, the IP address is wasted, but in VLSM, the smallest IP address is wasted.
To understand their differences more intuitively, you might refer to the following table.
Public vs Private IP address: what are the differences?
This post shows you differences between public IP address and private IP address.
Final Words
Its time to make a conclusion.
From this post, you could know what VLSM is and what the difference between it and FLSM is.
Besides, it’s possible for you to learn the procedure of implementing VLSM.
I believe that this post is helpful to you.
