If Netflix detects VPN IP addresses, it will display the streaming error code m7111-1331-5059 and temporarily block your access to the Netflix servers. This type of ban isn't unusual, other streaming services (such as Amazon Prime Video, BBC iPlayer, and more) also have VPN bans. It's not illegal to use a VPN for Netflix. However, Netflix does not allow the use of services that can circumvent geographical restrictions.
The streaming service has the right to ban your account, but no cases of such activity have been reported. The best thing for Netflix is to keep all its users subscribed. Even though Netflix blocks VPN connections, it's still possible to circumvent the ban. You should use a VPN that constantly renews your IP addresses and has specific streaming servers.
No, Netflix doesn't ban users who use a VPN. However, you won't be able to see anything if Netflix detects that you're using a VPN. Just look for a VPN service you can trust to maintain your servers and software, so you're one step ahead of Netflix. If the IP address of your VPN servers is not on that list, Netflix will take your apparent IP address at face value and stream content based on the location of your VPN server.
If Netflix blocks the IP addresses of a VPN service, it can simply lease new IP addresses, either from the data centers that host its servers or from the Internet service providers (ISPs) and backbone providers that issue their IP addresses to those data centers. When the full scope of Netflix's use of geoblocking became apparent, VPNs stepped in to offer a ready-to-use solution. No matter how strict your security measures are, it's hard to see Netflix permanently block VPN services. Around the world, thousands of users suddenly discovered that their VPN for Netflix wasn't working when the day before they could watch their favorite content without problems.
Many high-quality VPNs now promote their ability to bypass VPN bans on Netflix and other services. It's worth noting that the best VPNs for streaming, such as NordVPN and Surfshark, have been working reliably with Netflix for years. Netflix is constantly blocking VPN IP addresses, but major VPN services are working hard to overcome Netflix's VPN ban. If you've tried a conventional VPN and you're still unable to use Netflix with VPN servers, there's another option you should consider.
At the time, Netflix took a firm stance against VPN service providers because it was in their best interest to keep them happy. If it were only dependent on Netflix, it would be a global platform that transcends licensing agreements without the need to use a VPN.
