My public IPv6 address

Post by KulaSurfer »


I have an ADSL connection with static IPv6 address. One time my ISP converted my home connection from dynamic IPv4 to static IPv6.

Now I made the following observation.

(i) My FritzBox WLAN Router tells me that my current public IPv6 address is XXX.

(ii) Your website at the same time tells me that my public IPv6 address is YYY.

XXX and YYY are different.
Can someone explain?

Best regards

Without knowing the specific IP addresses I can only make an educated guess. Because there are so many more public IPv6 addresses your ISP may be allocating a block of addresses to your router, which it, in turns assigns a unique one to each of your devices. One way to test this would be to visit our site from a several different IPv6 enabled devices on your network and see if each one has their own IPv6 address.
