Program Settings
 * Auto Run
   If disabled, the app will only check the local IP and will not run tests
   automatically.
   
 * Multiple Connectivity Refreshes
   When enabled, the app runs five checks at startup and displays the lowest
   latency.
   
   
   
 * Pop-up Connectivity Alerts
   When enabled, the initial check's results are shown as a pop-up alert.
   





🔎 IP INFOS

The program will first check your IP address from different sources (including
IPv4 and IPv6), and then query the corresponding geographical data from the IP
geolocation source you selected. If there is only 1 IP stack, the source without
data will be displayed as empty.

Testing is done by loading small images from corresponding websites. Delay
values are for reference only and will be smaller in reality.

🚥 WEBRTC TEST

WebRTC often establishes connections directly via UDP. If the test returns your
real IP, it means your proxy settings do not cover these connections. In
addition to detecting the IP you use when connecting to WebRTC, we also detect
your NAT type. However, NAT type detection is not 100% accurate and is for
reference only.

🛑 DNS LEAK TEST

A DNS leak means that when you are connected to a VPN/proxy, your domain name
resolutions are still done through your local ISP, thus posing a risk of DNS
leaks.

The method to test for DNS leaks involves accessing a newly generated domain
name to detect which regional DNS exit you are resolving through. If the
endpoint region returned matches your local service provider's region, there is
a risk of DNS leakage. In this case, you may need to modify your VPN/proxy
settings.

🚀 SPEED TEST

Speed test will be done via Cloudflare's edge network, which may take a long
time. If your network is located in mainland China, the data may be biased. The
speed test results are for reference only, the actual speed will be faster. You
can choose the packet size for download and upload tests. By default, the speed
test will perform 4 rounds of packet uploads and downloads, please be mindful of
data usage.

About
AboutChangelog

IPCheck.ing is a free IP toolbox that helps you check your IP information, test
website availability, examine DNS exit information, perform speed tests, global
latency tests, MTR tests, and more.

This is an open-source project, and you can view the source code by clicking on
the GitHub icon at the bottom of the page.

Initially, this was a personal project for me to learn Vue.js and how to write
code using ChatGPT. Over time, it gained more stars on GitHub, so I did a lot of
refactoring and added many useful features. I hope you will enjoy it.
