IP calculator web application

The primary goal of this project was to develop an IP subnet calculator application capable of calculating complement ranges for user-defined subnets. This functionality is particularly useful in scenarios such as IP whitelisting or blacklisting, where users need to implement allow/deny rules in firewalls or even manage IP ranges for marketing campaigns.

Additional feature was introduced to enhance the calculator: it can now consolidate a list of individual IP addresses into optimized IP ranges. This feature is invaluable for users managing thousands of IP addresses.
