Catalogs vary a lot from country to country; some titles are only licensed for specific regions and only show up once you connect from that country. How strict the region lock is, and what setup it calls for, varies by platform:
Region lock strictness and the recommended proxy setup, by platform| Platform | Region lock | Recommended IP | Session mode |
|---|
| Netflix | Medium to strict — per-country catalog checks | Residential or ISP proxy | Sticky |
|---|
| Twitch | Loose — most streams are open | Residential proxy | Sticky (watching) / Rotating (multi-country testing) |
|---|
| YouTube | Loose to medium — ads and recommendations shift by region | Residential proxy | Sticky (watching) / Rotating (testing) |
|---|
| BBC iPlayer, ITVX (some UK services) | Strict — some check for a real UK ISP connection, not just a UK IP | ISP proxy (UK) | Sticky |
|---|
On Twitch and YouTube live streams, region locking is usually looser, but viewer counts and ad delivery vary by country, so measuring real visibility across markets can require connecting from several countries at once.
The practical rule: if you're opening a session and watching for a while (a show, a movie, a live match), you need a sticky IP — otherwise the player tries to re-verify your location mid-stream and playback breaks. But if you're quickly checking catalogs or region locks across many countries at once, a rotating pool that swaps IPs automatically per request is much more practical than switching countries by hand every time.
