Local IP Address
A tool to help you understand how hackers, trackers and ISP's track your browsing behavior.
This web app runs multiple tests to determine what data your browser is currently exposing about your online identity such as your IP address, DNS servers and WebRTC data leaks. The Advanced DNS test is especially unique in that it also helps test whether DNSSEC and DNS over TLS is enabled. It's a progressive web app using the power of service workers to deliver blazing fast test results. Service workers are a relatively new web standard that enables web apps to take advantage of smart caching of data to dramatically improve page loading times. Save this web app to your device homescreen for even faster results with one tap convenience.
Knowing how much of your digital fingerprint is being exposed by your browser is an important step toward protecting your online privacy and security. If you want to protect yourself against ISP's, corporations and governments selling your data without permission, it helps to understand what tools are effective. If you're using a VPN, proxy service and/or privacy plugins and still seeing your current location in the test results, then most likely your browser is still leaking data.

Your IP address reveals more about you than you realize, from your physical location to what sites you’re looking at.
At its most basic level, an IP is the address assigned to your computer by the company you’re using to access the internet. The process is automatic — your computer sends out a request to join the network, the network says, “Hey, come on in!” and then it assigns your computer an IP address. Your computer doesn’t own its IP — it changes if you access the internet from a new place or if the “lease” on the address runs out.
While the most common thing an IP address can reveal about you is your general geolocation, it is possible for government officials or hackers or your employer to put together a browsing history based on your IP address. They can also see who you’re sending emails to and who is sending emails to you, if they have the know-how. And if they decide that something you’re doing is illegal — or if someone else is using your IP address to commit illegal acts — that’s really bad news for you.
If you’re using a VPN, however, your real IP is hidden and to outsiders and it looks like you’re accessing the internet from a different location. Your browsing history should also be hidden but there are occasionally leaks. This IP test helps you determine if there are data leaks within your VPN. For example, if you can still see your current location? There’s a data leak.

DNS leak tests are important because they reveal whether or not your online activity is private.
Domain name system (DNS) servers translate that human web address that you type into the browser (the domain name) to computer language (the IP address). When you type an address into your device, it reaches out to the DNS to find out what number (IP address) is associated with that domain name. It then connects to that IP address and brings you to the site.
DNS servers are essential for getting online, but they’re also a major security risk. That’s because hackers create websites that look like your favorite sites but aren’t actually your favorite sites. In that situation, your computer reaches out to the DNS server, the thieves intercept it, and you’re redirected to a fake site that the hackers have control of. On that fake site, all of your information is now monitored — any password, for example, or online communications can be intercepted by thieves.
But there are ways you can protect yourself! Virtual Private Networks (VPNs) secure both your location and your data. However, there can be leaks in a VPN — which is where the DNS leak test comes in.
With a DNS leak test, you can see if any of your traffic is leaking out of the private network you’ve established. If that’s the case, your activity isn’t secure — which is definitely something you should be aware of if it’s happening.
Test your DNS servers and check if DNSSEC and DNS over TLS is working.

Compared to other DNS test sites, we built a DNS testing service that can provide a more complete picture of your DNS security settings. Knowing the companies and servers that are managing your traffic responses are important, but also knowing how these DNS servers have been setup will help reveal just how well your online privacy is protected or not. Tenta's Advanced DNS Test returns key test results such as:
Is DNSSEC enabled? - DNSSEC, aka DNS Security Extensions, provides additional security by enabling DNS responses to be validated. In other words, a layer of trust is added by confirming the domain you want to visit has been authenticated and validated. For this reason, DNSSEC helps fight against DNS spoofing.
Is DNS over TLS working? - TLS or Transport Layer Security is the successor to Secure Sockets Layers (SSL) protocol and encrypts your DNS traffic. That means nobody can see the sites you are requesting to visit. DNS over TLS helps prevent malicious hackers from sniffing your DNS queries and man-in-the-middle-attacks.
This is a relatively new cryptographic protocol and even the most reputable companies have not yet implemented this setting by default. Because of this reason, if TLS is disabled, but at least DNSSEC is enabled, we grade this is a Neutral setting instead of giving a warning. As the adoption rate of DNS over TLS increases, we will reconsider the grading level.

How WebRTC exposes your IP address.
Web Real-Time Communication (WebRTC) is an open source project that allows computers to communicate directly with each other, peer-to-peer. Instead of requiring plugins for things like audio and video calling or peer-to-peer file sharing, WebRTC makes it possible for apps to communicate plugin-free. It’s also a feature that’s built in to most browsers, and for good reason — it makes so many of the actions most of us take online every day a lot easier.
However, a security leak was exposed in WebRTC for Windows users who use Chrome or Firefox. In 2015, it became clear that the IP addresses of people using Virtual Private Networks were easily discoverable using just a few lines of code. Since that time, some VPNs have sealed the leak — but not all.
With the WebRTC leak test, you can see the IP address and location that is revealed by your browser’s built-in WebRTC program. It’s great way to test whether or not your VPN is truly keeping your IP address private.

If your IP address is blacklisted, that means it’s been identified as an IP that’s associated with spam.
If your IP address is on a blacklist, you won’t be able to send out emails — a major inconvenience in this day and age. Blacklists are compiled by email servers and spam filters, but there’s no central blacklist that keeps track of everyone. As a result, you might be on one black list but not another, or you might be on multiple blacklists.
There are a couple of ways you can get on a blacklist and they all have to do with spam: either you’ve been flagged for sending out spam emails; your IP address was included in a range of IP addresses that were tagged as potentially sending spam; or your IP has been flagged as being from a country or internet service provider that doesn’t honor “unsubscribe” requests.
So if you find out that you’re on a blacklist, there are steps you can take to get off of it. First of all, you need to make sure that your computer isn’t sending out spam without your knowledge. Scan your system for viruses and then make sure your operating system is up to date. Ensure that your routers are securely configured and reset all of your passwords so that they’re stronger than they were previously.
Once you’ve done all of that, some blacklists will let you self-remove your IP address. Others have time limits and will automatically drop any IPs that aren’t serious spammers within a couple of weeks. However, if your IP has sent out a lot of spam, it might take longer. Be patient! If you’ve taken all the proper steps to ensure that it won’t happen again, you should be removed from the list with time.

Your flash browser plugin may be exposing your IP address, even with a VPN.
Flash browser plugins allow your browser to show programs that are powered by Flash, like animations, videos, and games. Flash used to be huge but in recent years has become less essential as new software replaces it.
One of the reasons Flash has been pushed out of popularity is the fact that, historically, it has had some really major security leaks. Both user’s failure to update the plugins and faults within the plugin itself have made it a great target for hackers. Also, even un-hacked, Flash can reveal a lot of information about you that you might not want public. For example, it’s easy to figure out what operating system you’re running and your IP address.
VPNs can hide your IP but Flash is another weak point where your IP might be sneaking through, even if you’re running a VPN. A flash leak test will let you whether your VPN is doing it’s job or whether you’re exposed.

Your HTTP headers are stocked with a ton of info
The full web address you type into your browser starts with either “http” or “https.” After you’ve entered the address, your computer sends a request to the server and the server responds, allowing you on to the site you’re trying to access. Within that request and response are a series of HTTP headers that tell the server and site you’re trying to access a range of information including what browser you’re using and what operating system you’re running.

What are Tor exits and who uses them?
Tor is a free software that helps users communicate and access the internet anonymously. It functions
through a series of volunteer-run servers located around the world that use virtual tunnels instead of
direct connections. Because the servers are hidden and each request bounces through at least three
servers, users are protected from everyone from advertisers looking to track their activity in order to
target them for ads to governments trying to spy on them to censorship of certain sites.
A Tor node is one of those volunteer-run servers. There are three types of Tor nodes: middle relays, exits, and bridges. A middle relay is one that receives Tor traffic and passes it along to the next relay. An exit is the final node that information passes through before reaching its final destination. It’s also where Tor traffic appears to be originating from because its IP address is assigned to any traffic that comes out of it. A bridge is a part of the network that isn’t publicly listed and is used for traffic to and from places (like China) that block publicly listed Tor relays.
With this test, you can determine whether or not your IP address has been identified as a Tor exit node, which means you’re able to send and receive traffic on the Tor network. Unfortunately, this also means your browser may be blocked by some services who block IP addresses that are recognized as TOR nodes.
Your IP is not identified to be a TOR node.
A web tool to check your screen display resolution.
Do you know what your screen display resolution is? Your average user doesn’t — and doesn’t need
to. But if you’re developing a website or changing your web user agent, your screen resolution suddenly
becomes really important. That’s because the way you’re seeing images and colors on your screen will be
different from how users with a different screen resolution will see it.
Your screen display resolution is represented by two numbers. The first one is the number of pixels your screen displays horizontally and the second one is the number of pixels it displays vertically. Many web designers and developers choose screens with higher resolutions because they want the highest quality while they’re working, but users often have lower resolution screens. If you work in one of these fields, it’s important to know what you’re working with so you can tell how that’s affecting your work.
Available CSS resolution:
Note: The current method of obtaining screen width and height is not supported consistently across browsers, so you may notice slight differences depending on your browser.
What system information can your browser see?
Your system information can potentially reveal personally identifiable information, from what operating system you’re running to your IP address. This test card lets you know exactly what system information your browser can see and is also useful to quickly check what browser settings and plugins you’ve enabled.
