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 ...

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 ...

Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation indicates the total number of IP addresses available. Click here to see an enlarged diagram. Understanding ...

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 ...

Hi everyone... back from a hiatus of sorts. Not that I expect anyone to have noticed... Anyway, I work with PCs that have multiple bits of equipment attached to them via Ethernet. I try to put each ...

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 ...

Knowing how an IP address identifies a host on a network can be confusing. Before you begin calculating various addresses, you should know the fundamentals of IP addressing. Todd Lammle describes this ...
