(to those exclusively on the captive-portals list, this email follows on 
a discussion around a presentation discussing implications of DNS over 
HTTP in networks where captive portals are present)

As there are numerous folk from browser and OS vendors within this 
mailing list who implement capture portal detection, would there benefit 
in authoring an informational document covering capture portal detection 
methods in the absence of a network's DHCP service not implementing RFC 
7710? Such a document may help describe common methods to inform 
implementers and minimise detection evading capture portals. It may be 
better placed in the capport WG instead of doh.
