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 ...

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 ...

A subnet mask is a number that specifies which parts of an IP address represent the host and network portions of the address. These masks are 32 bits in IPv4 networks and 128 bits in IPv6 networks. A ...

A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an Internet Protocol (IP) network broken into multiple, smaller network ...

In the previous installment on UDP broadcasting and service discovery, the basics of both were explored, including an implementation in the form of NyanSD and its protocol. Contained in the comment ...

Almost every conversation I have with folks just learning about IPv6 goes about the same way; once I’m finally able to convince them that IPv6 is not going away and is needed in their network, the ...

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 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, ...

Before we can go into a detailed discussion of how to calculate the number of network hosts on a network, it is important to have a satisfactory level of understanding about where the whole concept of ...
