Abstract
In many environments offering short-term or temporary Internet access(such as coffee shops), it is common to start new connections in acaptive-portal mode. This highly restricts what the customer can dountil the customer has authenticated.
This document describes a DHCP option (and a Router Advertisement (RA)extension) to inform clients that they are behind some sort of captive-portaldevice and that they will need to authenticate to get Internet access. It isnot a full solution to address all of the issues that clients mayhave with captive portals; it is designed to be used in largersolutions. The method of authenticating to and interacting with thecaptive portal is out of scope for this document.
