-IP Utility Tools - IPv4 and IPv6
+# IP-Dash
+
+[![npm version](https://badge.fury.io/js/ip-dash.svg)](https://www.npmjs.com/package/ip-dash)
+
+IP address utility tool for IPv4 and IPv6
+
+## Installation
+
+```shell
+npm install ip-dash
+```
+
+https://www.npmjs.com/package/ip-dash
+
+## Features
+
+- Basic IP address validation and find the version of the IP address.
+- Find the scope of IP address - Public, Private or Loopback.
+- Get public IP address of the client in top matched order from `req`.
+- Convert both IPv4 and IPv6 to IP decimal format.
+
+## Usage
+
+```js
+const ipDash = require('ip-dash');
+
+// Checks valid ip address and returns the ip version 4 or 6 and 0 if invalid ip.
+ipDash.isIP('35.89.146.200');
+
+// Checks ip address is ip address version 4 and returns true or false.
+ipDash.isIPv4('35.89.146.200');
+
+// Checks ip address is ip address version 6 and returns true or false.
+ipDash.isIPv6('07b5:92e5:6f12:0315:6259:34bd:93ca:bbfd');
+
+// Checks ip address is a private ip address and returns true or false.
+ipDash.isPrivateIP('127.0.0.1');
+
+// Checks ip address is a private ip address and returns true or false.
+ipDash.isPublicIP('35.89.146.200');
+
+// Checks ip address is a private ip address and returns true or false.
+ipDash.isLoopbackIP('127.0.0.1');
+
+// Return the ip address of user from request in the order of X-Client-IP,
+// X-Forwarded-For, CF-Connecting-IP, connection, socket, info remoteAddresses.
+ipDash.getClientIP(req);
+
+// Returns the private ip address of the current running process.
+ipDash.getMyPrivateIP(); // Returns 192.168.0.4
+
+// Converts IP address to IP decimal.
+ipDash.ipToDecimal('35.89.146.200'); // Returns 593072840
+
+// Converts IP address to IP decimal.
+ipDash.ipToDecimal('07b5:92e5:6f12:0315:6259:34bd:93ca:bbfd'); // Returns 10247381111315175137996068065712454653
