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 ...

Have you learned to think and dream in hex yet? That is what you are going to have to look forward to as we transition to using IPv6. Because we will be working in hexadecimal numbers we may need a ...

I have a networking situation where some tools can or can't communicate between two devices on the same LAN but differing subnet masks (it's an error, will be corrected). The question is why do some ...

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 ...

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 ...
