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 ...

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 ...

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 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 ...

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 ...

I've got a DSL connection from southwestern bell. I checked the IP on my router, and see xxx.xxx.244.255. now, if I'm not mistaken, that should be the broadcast address...and my subnet mask is 255.255 ...

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 ...

Subnetting a Class C network can be a tricky process to master. From MCSE to CCNA to RHCE to CNE, you'll have to know it and know it well. Todd Lammle walks you through clear instructions and ...

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 ...
