The previous 2 posters were correct

6456:2ec is 100.86.2.236

Edit: ah you're posting your WAN IP.

So IPV4 is CGNAT with a 6to4 tunnel for IPV6. Who is the ISP? I want to know who it is I'm avoiding.

(as your router's WAN address): that proves you're on CGNAT. The range reserved for this is 100.64.0.0/10 (100.64.0.0 - 100.127.255.255)

If the "IPv6" address you're given is a tunnel address for another CGNAT IP, that's complete pants. It can't possibly work on the Internet, not without a ton of NAT66 at least.

What your ISP needs to do is:
1. Join RIPE (€1000, plus annual membership fee of €1550)
2. Get a /32 IPv6 allocation (€50 one-time fee)
3. Announce it to the Internet and assign /48 or /56 chunks of its to their customers

It is Wildanet, it is the only fibre available to us. I an thinking about a static IP address but they haven’t got back to me when I asked if the IPv6 would be native.
