no public ipv6 address when shared to other computers is selected

cn flag

I have no education about networks or subnets and how ipv6 works, so here is the problem.

I have Ubuntu mate 20.04 installed on a machine which is connected to the internet vai android WiFi tethering.

I want to share my internet connection through an Ethernet port of the Ubuntu machine to my router's wan port.

I edited the wired connections setting and under ipv4 and ipv6 tabs in my Ubuntu machine and I selected Shared to other computers in both ipv4 and ipv6 tabs.

I gave a static ipv4 address of 192.168.137.1 in the Address option, but in ipv6 i didn't gave any static address and i don't know how to do so.

My router is connected to the internet right now but when I connect my mobile device or laptop to router's WiFi or Ethernet port and go to check my internet ipv4 and ipv6 address on google it only shows ipv4 public address and ipv6 is not detected.

I can't get my head around it why it is not working.

So here are my questions

  1. How to give static ipv6 address from Ubuntu to my router

  2. After giving static ipv6 address will I get a ipv6 public address when I connect to my router's WiFi

Now I want to point out that my Ubuntu machine is getting a public ipv4 and public ipv6 address on https://whatismyipaddress.com

My router is a d-link 2750u with 3 lan ports and 1 wan port

Here are image links ipv4 shared to other computers setting

All that detail and no mention of the version of Ubuntu or whether it is server or desktop.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
