this is my first post, so be gentle with me for sometimes not using the correct terminology.
I am using a Fibre ISP with CG-NAT (DS-Lite). I connect via IPv6 Prefix Delegation with a /56 address space. Since I have no static IP (IPv4) I chose to use an off-site Server to tunnel the ipv4-traffic via tunnel6 to my quasi-static IPv6 home address (ISP does not guarantee a static one but it is now for months).
When checking my WAN address I realized that via ifconfig in my router there was a IPv6 address different from ipv6-test using my laptop, on my mobile a next one (via ipv6-test). And those aren't the link local addresses. The Prefix is of course the same, but the Identifier is different. All of those addresses (pingv6, traceroute6...) end up at my Gateway router.
To my knowledge and a lot of Internet search there should only be 1 WAN public IP. Could someone explain that to me or should I just be happy for multiple WAN IPs.
