Question 1

What is my IP address and what does it show?

Accepted Answer

Your IP address is a unique number your Internet Service Provider assigns to your device. An IP check on InstantIPCheck.com instantly reveals your public IP, approximate location (city, region, country), ISP name, and ASN — no signup required.

Question 2

How do I find my IP address and location?

Accepted Answer

Open InstantIPCheck.com in any browser. Your public IP address, country, city, ISP, and connection details appear instantly on the first screen — no extra clicks or downloads needed.

Question 3

What is a DNS leak and how do I test for it?

Accepted Answer

A DNS leak occurs when your DNS queries bypass your VPN tunnel and go through your ISP's DNS servers, revealing your real location. InstantIPCheck.com runs an automatic DNS leak test that checks which DNS servers are resolving your requests and flags any leaks.

Question 4

What is a WebRTC leak?

Accepted Answer

WebRTC is a browser feature for real-time communication that can expose your real IP address even when using a VPN. InstantIPCheck.com's WebRTC leak test detects if your browser is leaking your local or public IP through WebRTC protocols.

Question 5

Does a VPN or proxy change what I see during an IP check?

Accepted Answer

Yes. If your VPN or proxy is working correctly, the IP check will display the server's IP and country instead of your real network IP. If not, InstantIPCheck.com's leak tests will flag DNS, WebRTC, or IP leaks and location mismatches.

Question 6

What is browser fingerprinting?

Accepted Answer

Browser fingerprinting collects unique technical details about your browser — User-Agent, screen resolution, installed fonts, WebGL renderer, timezone, and more — to create a trackable identifier even without cookies. InstantIPCheck.com shows your full browser fingerprint so you can assess your privacy exposure.

Question 7

Is InstantIPCheck.com free and safe to use?

Accepted Answer

Absolutely. InstantIPCheck.com is 100% free and open-source. It only displays the technical data your browser and network already broadcast — IP, headers, and connection signals. No software installation required, no personal data collected or stored.

Question 8

How do I check if my IP is blacklisted?

Accepted Answer

InstantIPCheck.com includes an IP blacklist check that queries major blacklist databases to see if your IP address has been flagged for spam, abuse, or suspicious activity. Results appear alongside your main IP information.
