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 ...

Subnetting and creating subnet masks is often outsourced to consultants, but doing it yourself can be both challenging and rewarding. In the IT world, specifically in networking, there aren’t many ...

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 ...

The last editionof this column discussed subnet masks and the nature of IP addressing. In this and the following column, we will begin discussing what subnetting means and how to do it. First, though, ...

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 ...

To understand how subnetting works, you first must have a good basic understanding of IP addresses. An IP address is set of binary octets broken into quads. That definition may not have made any sense ...

If your company network is having problems and you need to troubleshoot it, you also need to know some basic information about the computers on the network. Internet Protocol is the underlying ...

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 bits in the mask identify both hosts and subnets. The more hosts, the fewer subnets; the more subnets, the fewer hosts can be individually addressed. These bits become a tradeoff based on the ...

The last edition of this column talked about subnets and introduced folding paper as an illustration of how subnets can be understood. This will be very useful as we proceed. MORE IPv4 SUBNETTING ...
