Hulu is region-locked because copyright and licensing agreements are sold by territory. To enforce these regional viewing restrictions, Hulu applies geo-restrictions using multiple signals. The core check is IP address geolocation, augmented by GPS/device location on mobile, time zone/DNS/WebRTC network hints, and account context captured via browser cookies, billing country, and household rules. Traffic suspected of coming from VPNs or proxies is blocked through server detection: blocklists of data-center ranges, anomaly scoring, and patterns across server fleets. A VPN may momentarily bypass checks but is unstable and may violate terms. Note that “PAL devices” refer to an old analog video standard, not modern streaming controls. Bottom line: if the combined signals point outside supported regions, access is denied, regardless of device.
