<strong>DNS</strong> & <strong>Iodine</strong><br />
Christian Grothoff<br />
Problem Statement<br />
Your “provider” offers an open WLAN network with<br />
browser-based authentication <strong>and</strong>/or payment.<br />
Specifically:<br />
• Your local ISP gives you <strong>DNS</strong>, but not IP service<br />
• “nslookup www.google.com” works prior to payment<br />
How can you go online anyway?<br />
