Easy to understand DNS server with captive portal trigger.

• Creates one DNS server and one HTTP server.
• The HTTP server handles the webpage.
• The DNS server redirects the trigger urls to the target address of the HTTP server.

• A router that support DNS redirection to a local device and the creation of an hotspot without the password.
• Any device that can run node.js. We'll call it server from now on.

• Connect the server to the router via ethernet.
• Assign a static ip address to the server.
• Set the server's ip address as the DNS server in your router's settings.
• Install node.js and npm in the server.
• Clone this repository in a directory of the server.
• cd to the directory and run npm install.
• Start the DNS/HTTP servers with npm start.
