HowTo - Disable the IPv6 Privacy Extension in Linux

It's possible that the IPv6 privacy extensions on your VPS have been activated. When this option is selected, Linux will generate its own address at random. When utilizing IPv6, this random address will not function and for security reasons, this is not supported on our platform. 


You can fix this problem by turning off the privacy add-ons.
To do so, take the following steps:

  1. Using SSH, log in as root and run the following commands: 
echo net.ipv6.conf.all.use_tempaddr=0 >> /etc/sysctl.conf 
sysctl -p 

After this is done, the operating system will switch to the default autoconfigured IPv6 address in a few seconds.
