Why your VPN keeps getting blocked by streaming services (and the fix)

You connect to a VPN to watch your home library while travelling. Netflix shows the wrong region. Or worse: a black-and-white "you appear to be using an unblocker or proxy" wall. This happens to nearly every VPN nearly every week. Here is what is happening, and the workflow that gets through.

How the streaming services detect you

Streaming platforms maintain rolling lists of IP ranges associated with VPNs and data centers. Three signals get an IP onto those lists:

• ASN (the network operator). Hosting providers like AWS, Hetzner, OVH, Scaleway, and Linode have ASNs that are easy to identify.
• rDNS (reverse DNS). An IP that resolves to "vpn-exit-04.somewhere.com" gets flagged instantly.
• Behaviour. Sudden spikes in account logins from one IP, or many concurrent streams from the same /24 subnet.

A VPN exit that is shared by 200 customers all watching Netflix from the same IP triggers all three. That is why VPN endpoints get burned within days of being public.

How we keep streaming working

Residential IPs on streaming-routed servers

For our streaming-optimised cities, we pay extra for IP allocations from residential ISPs rather than data-center providers. The ASN looks like a normal home internet customer. The rDNS resolves blandly. The streaming services do not flag these as "proxy."

Per-service routing

Inside our network, traffic to known streaming services is rerouted through these residential exits automatically. You do not pick a "Netflix server"; you pick a city, and we send Netflix-bound traffic via the streaming-clean exit while the rest of your traffic goes through whatever exit you chose.

Daily IP rotation in a small number of cities

In the cities that matter most — New York, Los Angeles, London, Tokyo, Sydney — we rotate streaming exits every 24 hours. If an IP gets burned, fresh ones replace it within hours.

When it still does not work — your troubleshooting checklist

1. 1Switch cities. Different exits even within the same country use different IP pools.
2. 2Switch protocols. WireGuard and Obfuscated WireGuard go out through different exits. Some services flag UDP-VPNs more aggressively than TLS-wrapped ones.
3. 3Clear cookies. Once a streaming site has tagged your account session as "originating from VPN," the cookie carries that flag even after you change IPs. Sign out, clear cookies, reconnect.
4. 4Use the app, not the browser. Streaming apps tend to be less aggressive than browsers because they cannot rely on browser fingerprinting.
5. 5Check for IPv6 leaks. Some clients leak IPv6 even when IPv4 is tunneled. Disable IPv6 system-wide, or use the kill-switch option that drops IPv6 entirely.

What about the "VPN unblocker" services?

There is a cottage industry of services that claim to specifically defeat Netflix etc. Most are reselling a small pool of residential IPs to thousands of customers. They work for a week and then stop. We do not recommend them; the residential IPs are usually botnet-derived, which is a separate ethical problem.

A note on legality

Using a VPN to access content from your home country while travelling is broadly fine — you are still a subscriber to a service you pay for. Using a VPN to bypass a region you do not have a subscription in violates the streaming service's terms (which is between you and them, not generally a criminal matter). We don't moralise about it; we route the traffic.
