Question 1

How do I check if my internet is working?

Accepted Answer

Visit isinternetup.com — if you can see the page, your internet is working. The site also runs diagnostics including DNS resolution, latency, speed tests, and more to give you a full picture of your connection health.

Question 2

What is a WebRTC leak test?

Accepted Answer

A WebRTC leak test checks if your real IP address is exposed through your browser's WebRTC feature, even when using a VPN. This is important for privacy — if WebRTC leaks your local IP, websites can see your real address despite VPN protection.

Question 3

How can I tell if my VPN is working?

Accepted Answer

The VPN Detection Hint compares your browser's geolocation with the location your IP address reports. If these are far apart (more than 100 km), it suggests a VPN or proxy is active. A match means your reported location is consistent.

Question 4

What is my IP address?

Accepted Answer

Your IP address is displayed automatically when you visit isinternetup.com. The site detects whether you're using IPv4 or IPv6 and shows your approximate location based on your IP.

Question 5

What TLS version is my browser using?

Accepted Answer

isinternetup.com detects and displays your TLS version automatically. Modern browsers typically use TLS 1.3 with HTTP/2 or HTTP/3. TLS 1.3 provides the best security and performance.
