Software description
Dividing subnets is a headache. If you want to divide a Class A IP into thousands of subnets, do you have to do the math by hand? Of course not! Subnet mask calculator!
This was just written recently. It can automatically divide Class A, B, and C IPs. It can output the divided subnet mask, subnet bits, maximum number of subnets, host bits, maximum number of hosts, and all subnet lists, and can save the results to a text file.
This software may add new features: supernetting and variable-length subnet masking. (I said it might be possible, because the algorithm for dividing subnets by variable-length subnet masks and the difficulty of processing strings have greatly increased, so I do not rule out the possibility that I cannot write it.) This software already has the function of automatically checking for new versions and server support. When the software releases a new version, you will receive a prompt and be directed to open this page.
