Each VPS is automatically assigned its own /64 IPv6 subnet with an IPv6 address statically preconfigured on the interface. To change the IPv6 address or add more addresses, manual configuration is required depending on the operating system in use. The subnet mask must be configured as /48, not /64. Additionally, a default route or gateway must be configured to enable external IPv6 communication with a specific address valid for the server location. Debian Linux users can use the ip command for network setup.
Each VPS is automatically assigned its own /64 IPv6 subnet by EDIS. An IPv6 address from the assigned subnet is statically preconfigured on the interface.
To change the IPv6 address or add more addresses from the /64 assigned to your KVM, you'll need to use a manual configuration. The network setup is dependent on the operating system in use.
In Debian Linux you can work with the ip command.
Keep in mind that the subnet mask must be configured as /48 and not /64.
Configure an IPv6 address at runtime:
ip -6 addr add 2a03:f80:ed15:435a::1/48 dev eth0
Display configured IPv6 addresses
ip -6 addr show
To enable external IPv6 communication, a default route or default gateway must be configured.
Configure an IPv6 default route
ip -6 route add default via 2a03:f80:ed15::1
Every server location has its own IPv6 default route! Only use the address valid for your server location!
