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.
