I have reviewed this document as part of the security directorate's effort to review all IETF documents being processed by the IESG.

These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comment.

This document communicates the presence of a captive portal in a WiFi network using DHCP and RAs.

Recommendation:  Ready

The motivation of the document makes sense, namely to avoid interception of traffic, and the document is an easy extension to already available mechanisms (RA/DHCP). I was expecting to see a reference to Hotspot 2.0, which aims to make the interaction between hotspot providers and end devices more intelligent (but covers a much larger scope).

Minor nit:

In Section 4 you write:

"This document defines two DHCP Captive-Portal options, one for IPv6

   and one for IPv6."

It should of course read "..., one for IPv4 and one for IPv6."
