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

implementers and minimise detection evading capture portals. It may be

better placed in the capport WG instead of doh.
