I’ve released updates for the Android app and the browser extension of my tools named both “IP Address & Geolocation” with a total of over 120000 downloads.
With the new updates you’re now able to see your IPv6 and get also alerts for these when they change.
This might help you while using VPN for example. So you can make sure that both of your IP addresses has changed. If you have no visible IPv6 then your ISP is not supporting it. Some ISP enable it on request, have a look.
