8 Steps to Understanding IP Subnetting

If a single physical network has more than one router, and the wrong router is configured as a default gateway, a host will be able to communicate with some remote networks, but not others.

Principles, Protocols, and Architecture," Tcp ip subnetting E. Glossary Broadcast address -- An IP address with a tcp ip subnetting portion that is all ones.

Internet -- The global collection of networks that are connected together and share a common range of IP addresses. Network -- There are two uses of the term network in this article.

One is a group of computers on a single physical network segment; the other is an IP network address range that is allocated by a system administrator. Network address -- An IP address tcp ip subnetting a host portion that is all zeros.

Octet -- An 8-bit tcp ip subnetting, 4 of which comprise a bit IP address. They have a range of that correspond to the decimal values 0- Router -- A device that passes network traffic between different IP networks.

Subnet Mask -- A bit number used to distinguish the network and host portions of an IP address. Subnet or Subnetwork -- A smaller network created by dividing a larger network into equal parts.

Wide area network WAN -- A large network that is a collection of smaller networks separated by routers. The Internet is an example of a very large WAN. For example, I used to work in an office in which thousands of users all worked in a single building.

Understanding TCP/IP addressing and subnetting basics

For a long time, there were no external facilities. In an environment like this, you can implement subnets, but the locations for those subnets might not be so clear. I have seen some companies subnet by department, but this tends to be a bad idea because it's not uncommon for a tcp ip subnetting to move to another part of tcp ip subnetting building.

Worse yet, a department might move some of its employees, but not others. A better solution is to rely on something that won't change.


For example, you might subnet by floor first floor, second floor, etc. Hopefully, you are starting to come up with a plan for your organization, but there is one more consideration that you need to make.

You need to stop and think about tcp ip subnetting placement.

All of the subnets will have to be linked together through a router you probably don't want to use the same router that connects your organization to the outside tcp ip subnetting. Therefore, you will need to figure out what size router you are going to need, how much that router will cost, where the router will be placed, and tcp ip subnetting the router will connect to each subnet.

Likewise, each subnet will need its own hubs or switches. You defeat the purpose of subnetting if multiple subnets are sharing a common hub.
