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 ...

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 ...

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 ...

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 ...

Hi. I have a rather technical and specific problem, and I know it's the wrong thing to do (especially since it doesn't work), but I'm trying to learn WHY it doesn't work. All subnets are 255.255.255.0 ...

IP addresses on your company network consist of three parts: the network address, the host address and the subnet mask. The network address identifies your broad network, and host addresses identify ...

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 ...

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 following summarizes how networks, subnetworks and hosts are identified in the TCP/IP protocol. An IP address is first divided between networks and hosts. The host bits are further divided between ...

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 ...
