How Does Netflix Know Which Device You’re Using?
If you’re an avid Netflix user, you must have stumbled on the devices connected to your account somewhere in the settings section of Your Accounts. Depending on your device type, Netflix can optimize video playback to suit your device perfectly.
Ever wondered how Netflix knows which device you’re using? There are a few ways they can tell what device you use, and it makes sense when you think about it.
1. Netflix Uses Device Fingerprinting
Device fingerprinting is the process of identifying devices accessing a site using their unique hardware and software features. Some of these features include your browser type, device’s operating system, screen resolution, and even hardware components.
When you connect to Netflix, the network analyzes your device’s features and compares them to its database of known device fingerprints.
Using the information gleaned, Netflix can monitor the use of accounts by connected devices. This is done by pinpointing any strange device trying to gain access to an unauthorized account. Another use of device fingerprinting for Netflix is optimizing the viewing experience.
For instance, Netflix may adjust the video resolution to ensure the video playback matches the device’s hardware capacity. If a device’s fingerprint indicates that it is a mobile device, Netflix may modify the user interface to suit the smaller screen size better.
The best part of device fingerprinting is that you do not have to worry about compromised privacy. Netflix can’t collect anyPersonally-Identifying Information (PII)from the device through fingerprinting. Rest assured that Netflix isn’t peeking at your private information.
2. User Agent Strings
Netflix can also determine your device through user agent strings. you could check your user agent by visitingWhatIsMyBrowseror a similar website.
User agent strings are lines of text in HTTP headers as a form of identification for the device requesting online access to a website. Think of it like an identity card stating the make and capabilities of the device requesting information from a webpage.
Netflix uses user agent strings to collect information about the operating system of the device you are using to stream. This information then helps Netflix display your device’s appropriate format and interface. User agent strings also help Netflix keep tabs on the number of devices connected to a particular account.
Overall, user agent strings are an essential tool that helps Netflix provide a fluid streaming service across different devices while maintaining the integrity of your account.
3. Netflix Also Checks Your IP Address
Internet Protocol (IP) addressis a distinct numerical identifier assigned to a device used to communicate and exchange data over the internet.
Your device’s IP address identifies your network interface and location. Netflix checks your IP address to know both your location and the type of device you’re using to stream your preferred movie or show.
This is important, as they have to check if your device’s location matches the country where you’re subscribed. If your IP address differs from the country where the subscription was made, you could be barred from accessing certain content or the entire streaming service altogether.
With IP checking, Netflix can ascertain what device you are using. If it is from a smartphone, tablet, smart TV, or even a gaming console, Netflix will know and tailor your video playback to be compatible with your device.
Netflix’s access to your location is solely for your viewing experience. Their servers are largely secure, so you need not worry about your personal information or location being given away.
All for an Optimal Viewing Experience
Netflix determines users' devices to limit the users and devices utilizing an account. Also, knowing the features of the connected devices helps Netflix curate a seamless streaming experience best suited for your particular device.
Fingerprinting, user-agent strings, and your IP address provide Netflix with the needed information to make that happen. All you have to do is kick back, grab popcorn, and enjoy your shows.
Netflix is a phenomenal streaming service packed with cool features and content. However, these tools can help make Netflix even better.
