ISPsystem introduced support of IPv6 in VMmanager 6. Now users can manage IPv6 addresses and allocate them to subnets now.
It was already possible to sell single IPv6 IP addresses in the previous version of the VMmanager. But it was also a problematic process because in server administration the system could not allocate more than 200 IPv6 addresses.
Subnets on virtual machine
But in VMmanager 6, users can allow subnets on a virtual machine so users can work with any number of IP addresses in the allocated subnet. In Billmanager, providers can sell IPc6 automatically.
You can follow these steps to add an IPv6 address to a virtual machine running CentOS 7. After connecting to the server through SSH with the superuser permissions, add “NETWORKING_IPV6=yes” string into the “/etc/sysconfig/network” file.
Open the file “/etc/sysconfig/network-scripts/ifcfg-eth0” and add the string at the end of the file:
IPV6INIT=yes IPV6ADDR=x:x:x:x::10/80 IPV6_DEFAULTGW=x:x:x:x::1
And finally, restart the service network.
