Validate and Classify Any IP Address Validate IPv4 and IPv6 addresses with type detection and range classification.

Under the hood, it uses React's useState and useCallback hooks to manage user input and validation results. When a user enters an IP address, the validateIp function trims the input string and checks if it contains a colon to determine whether to call the validateIpv4 or validateIpv6 function. The validateIpv4 function splits the input string into four octets using the dot as a separator and checks each octet against a regular expression to ensure it is a valid number between 0 and 255. It also checks for leading zeros in each octet.

The validateIpv6 function uses regular expressions to check if the input string conforms to full or compressed IPv6 notation, including the :: syntax. If the input string is valid, both functions return an object containing a boolean indicating whether the address is valid, a string specifying the IP version, and an array of strings providing detailed feedback about the address classification and format. The tool uses JavaScript's built-in parseInt function to convert octets to integers and its toString method to convert integers to binary strings for IPv4 addresses.

It also uses React's JSX syntax to render the user interface, including a text input field, a button to trigger validation, and a div element to display the validation results. The UI is styled using CSS classes, including glass-card, glass-input, and glass-button, which are defined in an external stylesheet. When the user clicks the Validate button or presses Enter, the handleValidate function is called, which updates the result state with the validation outcome and triggers a re-render of the component to display the results.
