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 ...

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 ...

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 ...

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 ...

Today, the standard methods for moving the network/host address boundary are variable-length subnet masking (VLSM) for host addressing and routing inside a routing domain, and classless interdomain ...

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 ...

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 ...

If you're looking to segment a TCP/IP network, subnetting is not your only option. CIDR, or supernetting, is another way to accomplish the task and offers some unique solutions. Here's how to use ...

I have an Excel spreadsheet containing IP addresses and subnet masks. I need to derive the subnet of each IP address in the spreadsheet.<BR><BR>Example: IP (column A): 10.1.230.84, Subnet Mask (column ...
