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 ...

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 ...

I feel stupid asking this, but I have always had a hard time understanding subnets no matter how much I have read on them. I always end up more confused than when I started.<BR><BR>What I do ...

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 ...

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 ...

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 ...

If computers in an open network talk freely with one another and two computers start talking at the same time, you have a “data collision.” Collisions may be arbitrated via Carrier Sense Multiple ...

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 ...
