TCP/IP Subnetter
The subnetter will ask you to enter the network portion of your TCP/IP address. Remember, for class A addresses, this is the first byte of the address, for class B addresses it is the first two bytes of the address, and for class C addresses it is the first three bytes of the address. You will also be required to enter either the number of subnets you require or the number of hosts you required.
The subnetter will then work out the following:
After this information is entered, you can display the address range for that given network address. This will be the first and last valid TCP/IP address, and the broadcast address for each subnet. In some instances, only the start of the subnet range will be displayed purely because the list is too large to display.
NEW in Version 3.11
With this new version, I have added two new functions in the subnetter. Firstly, a registered user can now capture the output to an ASCII file. Secondly, registered users can now use the NEW Class C variable subnet wizard. This new wizard will calculate the variable subnet masks and address ranges for up to 30 subnets for a class C address.
