We found several utilities to help calculate IP subnets, subnet ranges, and CIDR addressing. IP Subnet Calculator (free) is a good, basic subnet calculator that shows available subnets based on IP ...

For one to be able to create multiple logical networks within a Class A, B, or C network, one needs to know the principle of subnet. Without using subnets, one could only use a single network no ...

Subnet Mask divides the IP address into two segments and informs the computer which part is the network bit and which one is the host bit. For example, if there is an IP address: 192.168.0.1, it will ...

A subnet allows the flow of network traffic between hosts to be segregated based on a network configuration. By organizing hosts into logical groups, subnetting can improve network security and ...

Supernetting was created as a way to solve the problem of routing tables growing beyond our current ability to manage the exhaustion of Class B network address space. Much like one area code ...

The mask Class A subnet masks must start with 255.0.0.0 at a minimum, because the whole first octet of an IP address (the IP address describes the specific location on the network) is used to define ...

Hey all, I'm looking for an easy funtion that I can use in a BASH script (preffered a bash function) to calculate the IP Range/CIDR based off an IP and SUBNET Mask ...
