A captive-portal lab records browser and OS captive-detection endpoint probes. Why do assessors care about those probes?
Select an answer to reveal the explanation.
Short Explanation
Phones and laptops phone home to special URLs asking, "Am I stuck in a portal?" Labs that ignore those checkups wonder why the login page never pops. Design for the probe, not against it.
Full Explanation
Modern operating systems and browsers issue HTTP(S) requests to well-known captive-detection endpoints after joining a network. Portal labs commonly intercept or answer those probes to trigger the captive UX. The probes are unrelated to WPS PIN recovery and do not replace DHCP. Understanding this behavior improves reliable portal presentation in authorized tests.
