I have just started to use virtualmin on my vps server. Somehow my Ipv6 was different then my vps ptr record on my website. I read here forms and I understand that I need to change IP adreess to IPv6 which I have ptr record on it. To do that first I went to networking ->network conficuration ->Network interface->Activated at boot and add new record for eth0 with desired IPv6 and also my old IPv4 (this one I don't need to change) then I restart my vps and I wen to wirtualmin / server configiration -> Change IP adress. Ipv6 was there under the list as -shared address I chose this one and again restart my server.
Now I can see my IPv6 adress under system information -->IP address allocation, it is excatly how I want.
Here is the problem I did this one on friday so it is more than 48 hours but still when I check my nslookup on cmd command line I am seeing my old IPv6. Well I know it takes time to update IP changes but 48 hours?
Am I doing someting wrong or I just need to be more patient?
P.S. I need IPv6 on ptr recorded version because google refusse emails from my server.
Thanks in advance for your answers and time. Victor
