It is fairly common for organizations to want to subdivide their networks into smaller pieces for manageability purposes. Subnetting breaks a large network address space up into manageable pieces that administrators may assign to smaller subnetworks. In this video, learn how to subdivide large networks using IP subnetting.
- [Narrator] It's fairly common…for organizations to want to subdivide their networks…into smaller pieces for manageability purposes.…This is where IP subnetting can…provide an effective solution.…Subnetting breaks a large network address space…up into manageable pieces that administrators…may assign to smaller networks.…For example, assume that you're using…the 192.168 private address space on your network.…You might have a network that looks something like this…with different departments connected to…different geographic regions.…
Instead of haphazardly assigning addresses…throughout your network you might decide…that you want to use subnetworks.…The 192.168 address space normally has the dividing line…between network and host addresses here,…giving us a single network with…over 65,000 possible host addresses.…If we shift the dividing line to here…we now have 256 possible subnetworks…with 254 possible hosts each.…
We go from one network with over 65,000 hosts…to 256 networks with 254 hosts each.…While they may not all fit on the screen you get the point.…
