IP addresses allow web-connected devices to find and communicate with each other. Without specific IP addresses, devices wouldn’t be able to send and receive information from each other over the internet.
Another purpose of IP addresses is for location addressing. When a tool like ours detects an IP address, it queries a database (e.g. ARIN) to find the geographical area where the IP address is mapped to. This ‘area’ is known as your IP’s geolocation.
IP address locations are not the most accurate, but they do reveal in which city you appear to be located.
Why Is My IPv4 & IPv6 Address Different?
There are two types of IP address protocols in use: IPv4 (IP4) and IPv6 (IP6).
IPv4 uses a 32-bit address structure, which supports roughly 4.3 billion IP addresses. An IPv4 address typically looks like this: 192.0.2.235.
IPv6 was introduced to solve the IPv4 scarcity problem. It uses 128-bit addresses, which allows for up to 340 undecillion IP addresses. This is what an IPv6 address looks like: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
If you’re connected to a VPN service while using our tool, you may see different information between your IPv4 address and your IPv6 address.
This is most likely because your VPN is not tunneling IPv6 correctly. This means your real IPv6 address, and all the data associated with it, is still publicly exposed.
There are two ways to fix your VPN leaking your IPv6 address:
Check if your VPN has IPv6 leak protection within the app’s settings. If it does, make sure it’s enabled.
See if your VPN can disable or block IPv6. This is the next best option – your VPN will simply disable your IPv6 connection to prevent leaks, rather than attempt to tunnel it.
If you cannot find either of these options, your VPN cannot fix the problem.
In this case, you can attempt to fix the issue within your device’s network settings by manually disabling IPv6.
Web proxies are typically set up on an application-by-application basis, e.g. via a web browser.
When you connect to a proxy server, your IP address changes to one assigned by the server. This masks your true IP address while using a proxied application, and the websites you visit only see the proxy’s IP address.
