Domain is not reachable
I have created dns name server but my domain is not reachable. Although I can access my website with IP address.

I can ping that domain from Oregon (Seattle ISP) and from the Linode Fremont datacenter in CA. I was able to reach your website from Oregon as well. Perhaps, your domain info is still propagating.
However, ping6 doesn't work at all. You should set up A/AAAA records for your IPv6 address as well. You use the same procedure as you did with the IPv4 address, just use the IPv6 address that was assigned your Linode.
