What is this: A subnet calculator

Functionalities:

• CIDR calculation
• VLSM calculation

Java version required: 20+

Check out the releases

How to run:

java -jar SubnetCalculator-1.0-SNAPSHOT-jar-with-dependencies.jar or maybe just click it (haven't tried it in Windows or actually clicking it in the GUI, I just used the CLI)

Limitations:

CIDR

• It only stops at /30, so if you were to ask for a 100 subnets in a /24 mask, it would give you 64 subnets instead since it cannot go beyond 30 (I'm gonna implement an error panel next time to inform the user about this)
• Amount of networks displayed is only limited to 1024 to prevent lag, especially with networks that reach in the millions

VLSM

• Number of departments is only limited to 100 ( I don't believe you're gonna calculate for more than a 100 departments)
