If you ever get your ipv6 pings to work please post back here, I'd sure like to know what does it. In short I think it has to do with routes, but I think there is a solid way to do it. Any help is appreciated.

fe80 is the Link Local Address. It's used for communication between two nodes on the same segment. It's a SLAAC address, that is the host part contains the MAC address. It's the replacement for Gateway in IPv4.
eugene1973 Don't forget, ask your ISP if you get an IP address higher or a little lower than 2a00
My current IPv6 address from ISP is 2a00:4580:100:2f70:200:XX:XXXX:0. Is it wrong?
You must find the ipv6/dhcpv6 client settings to do this.
Unfortunately, I don't have an additional information, all that I know in my first post, sorry about that.

Sure. But I concern maybe something wrong with my router. Probably some hardware issue. I'm thinking about replacing this unit with a new one.
As I have said, 3 address ranges is probably default. If you are missing one range you are missing some traffic on the connection. It's not optional, and yes it might disrupt ping. I may have given you wrong info about the Windows command to find the info about publish. Rest assured it does exist. I'll try the commands in windows again to see which one it is. I mean it, you may really need three of those constructor code entries
The ISP WILL give you the address range information. If you have a common ISP then you can dig around on the web for them. It's common for people to pass this info. Don't be afraid to ask a techie at the ISP company.
You are that far with that router. Don't give up. I bet you'll find yourself in the same or worse a spot then you are now. It's not the router. It's a lack of code in it.
Where is this DNS server located? Does it respond to ping?
I'm not sure. sorry about that. I'm getting this address from my ISP. And yes, it responds:
Code:
PING 2a00:4580:100:2f70:200:ff:fe00:0 (2a00:4580:100:2f70:200:ff:fe00:0): 56 data bytes

All I have is only one address from ISP, I'm getting this automatically. I'm not aware of some additional information. They said that this address and these parameters are enough for IPv6 connection. And probably it's true, because of my direct connection through Windows with creating PPPoE connection there works perfectly.
May I ask what makes your ping work, exactly? Full config plz. Wait, is that your computer address or an external? You need to see this saying "yes" publish.
Per Yngve Berg Wrong. Your isp is not giving you a single address. It's full sub-net (2a00:4580:100:2f70::/64)
Hm.. Is that possible to get the whole subnet from ISP using this router?

I've just figured out finally that was a local address of my router. I'm not sure why this address showed as DNS address on my Windows PC. Just forget about that.
Here is my netsh interface ipv6 show route on my Windows PC:
C:\Users\Probity>netsh interface ipv6 show route

You must add the proper routes.
Should I add routes on the router?

I've just investigated a bit more. Tried with the router and without it.
Well, it seems I really getting the whole subnet, 2a00:4580:100:2f70:200:ff:fe00:0, this one. But why it is wrong? My ISP obligates to use DHCPv6 with PD. According to Wiki, the ISP must give me a subnet, but not the single IPv6 address. So, everything goes well.
When I don't use the router, I'm able to connect via PPPoE connection on my Windows PC. Then I'm getting IPv6 address like 2a00:4580:100:2f70:c4e4:8825:XXXX:XXXX from ISP. Everything works perfectly, all IPv6 tests pass, sites open.
When I use my router, I'm getting a similar address, but little bit different: 2a00:4580:100:2f70:98ef:f1d1:XXXX:XXXX. I concern about last 4 segments, but I guess this address belongs to my subnet from ISP at least. Well, it seems everything must work, but it doesn't.
I guess there is something wrong with DHCP server on the router. But I tried to follow all pieces of advice from here and from other sources.
Well, Dhcp6s and Radvd. Should I use them simultaneously? I think not. Only Radvd is in remain then. Here is my current DNSMasq config.
I'm not sure how it's possible to improve it. I played with parameters here a lot but got no working combination. And I'm not sure it has to be here or not. The fact that there is another option "Radvd custom" makes me frustrated.

I wonder if you ever found the issue. I am having the exact same behavior you have described
