|Target||information in field||Explained|
|Single host||host <address>||host indicates it's only that host|
|Single host||<address>||Single address, asuming 0.0.0.0 mask.|
|Single host||<address> 0.0.0.0||The mask of 0.0.0.0 indicates that there is no wildcard, only that address.|
|Entire Network||<address(network)> 0.0.0.255||the last bit (255) is the mask for the wildcard, every one bit will be a wildcard.|
|Entire Network (example 2)||<address(network)> 0.255.255.255||This example would be for a (ex) 10.0.0.0/8 network.|
|Everything (Wildcard)||0.0.0.0 255.255.255.255||mask of 255.255.255.255 indicating every bit is a wildcard.|
|Everything (Wildcard)||any||the word any indicates a wildcard.|

Full guide to using my Variable Lentgh Subnet Mask Calculator; This will hopefully clarify the features of the following calculator that can be found on my site:
It can be used to calculate subnets, but also to automatically calculate complete networks.
In this case you wil only have to fill out the first field that by default has "192.168.2.1/24" entered in it, this also is the field that will be highlighted when you come to the page, here you can type your IP address and add the Subnet mask by using a slash and then the subnet mask. You can also leave away the / and enter your mask in the little field next to the IP field. If you enter the subnet mask in the IP field the subnet mask field will be ignored.
Your results will be displayed in the output field, you can click the little copy buttons to copy the values to your clipboard.
There are a few ways to do to this, the easiest way to do this is by entering your network address in the IP field and then select the "Hosts" field. Type the number of hosts you need per network in this field and press enter, you should also see a table come up below.
You can just continue, you will need to check for yourself if it's still within your range.
The more polished way to do this is by first entering your range in the IP field, and adding that to the table by opening the table, adding a note and then clicking the "Store information" Button, After this you can update the subnet mask to what you need it to be (you will have to calculate what subnet mask you need by yourself.) add a new note. Then click "Store information and go to next network", this will store the information and update the IP address, you can now enter a new Subnet mask and continue.
The result will be a nicely formatted and well made up table, this table can also be copied to an Excel spreadsheet or a word document(Excel Recommended).
