[Dnsmasq-discuss] DHCP option for Captive Portals

[Donald Chisholm]

Hi all,

Recently I have noticed that on connect some wifi hotspots provide a popup
message indicating that the user must login to obtain Internet access.
 Since the user has not yet opened a browser I figure this feature is
implemented via a DHCP option.  I found references to the
proposed Captive-Portal identification in DHCP draft-wkumari-dhc-capport-00
(http://tools.ietf.org/html/draft-wkumari-dhc-capport-00) which seems to be
what I am looking for but it does not mention a proposed option number.

Anyone here know what the option is called or can point me in the direction
of how this may be implemented.

Thank you for reading,

Doanld
