When I’ve ping one server’s ipv4 adress from another server with ping command it is pinging. But If i try to ping with ipv6 adress from one server to another it is not working. I’ve tried ping6 command too.

Do you mean something like the following is not working in your case?
[flip@flop ~]$ host has address has IPv6 address 2404:6800:4006:811::200e mail is handled by 10

[flip@flop ~]$ ping 2404:6800:4006:811::200e

Not exactly. I’ve connected to one vm in cmd. From there I’ve done ping test for another vm with ipv4 adress which is pinging. Where as if i try to ping test the same remote vm with ipv6 adress (through ping &ping6 commands) it is not responding.
Try this
ping -6
and see if it is reachable

Check if you have IPv6 support on your system Use this command and observe its output:
ip -6 route

If you have a domain name and you want to get the replies from the IPv6, use the ping command like this:

ping -6 domain_name 
ping IPv6_address
This should be in either Linux Networking or one of the Server subcategories. Getting Started is for people trying to choose or install a Linux Distro.

If someone can advise me, I'll move it to the appropriate forum.

Have you tried working out step by step from the host?

Try ping6 on localhost. Next, try it on the local IPv6 address (starts with fe80...). Next, try ping6 on its real LAN IPv6 address.

Next try ping6 on another host on the same LAN and visa versa.

Can you ping6 the router's IPv6 address on the LAN? Can you ping6 its public IPv6 address on the WAN?

Does your router offer a test capability? Can you ping6 out to the internet from there?

... you get the idea.
Thanks Your Lordship - moving it there.
