Enable IPv6

you can enable ipv6 on dedicated core servers and vcpu servers when you create them or after you create them you can set up ipv6 to improve the network connectivity for your virtualized environment by setting up ipv6 for your dedicated core servers and vcpu servers, you can ensure that they are accessible to ipv6 enabled networks and clients prerequisites before enabling ipv6, make sure you have the appropriate privileges the contract administrators, owners, or users with the create vdc privilege can create new vdcs the number of bits in the fixed address is the prefix length for data center ipv6 cidr, the prefix length is /56 ensure the vdc has ipv6 enabled https //docs ionos com/cloud/network services/vdc networking/ip address/ipv6 to configure ipv6 on dedicated core servers or vcpu servers in the dcd , go to menu > virtual data centers select the data center where the server is configured select the respective dedicated core server or the vcpu server in the workspace to enable ipv6 for the selected server and to connect it to an ipv6 enabled local area network (lan) select the network tab on the inspector pane for the specific server and enter the following name it is recommended to enter a unique name for this network interface controller (nic) mac this field is automatically populated lan select an ipv6 enabled lan firewall specify whether you want to enable or disable the firewall for enabling the firewall, choose ingress to create flow logs for incoming traffic, egress for outgoing traffic, or bidirectional to create flow logs for all traffic flow log select + to add a new flow log enter name, direction, action, target s3 bucket, and select + flow log to complete the configuration of the flow log it becomes applied once you provision your changes ipv4 configuration this field is automatically populated if dynamic host configuration protocol (dhcp) is enabled, the internet protocol version 4 (ipv4) address is dynamic, meaning it can change while the dedicated core server is operational or in the case of a restart add additional public ip addresses in add ip it is an optional field ipv6 configuration you can populate a nic ipv6 cidr block with prefix length /80 or allow it to be automatically assigned from the vdcs allocated range, as seen in the screenshot below add additional public ip addresses in add ip it is an optional field setting up ipv6 for dedicated core servers name it is recommended to enter a unique name for this network interface controller (nic) mac this field is automatically populated lan select an ipv6 enabled lan firewall specify whether you want to enable or disable the firewall for enabling the firewall, choose ingress to create flow logs for incoming traffic, egress for outgoing traffic, or bidirectional to create flow logs for all traffic flow log select + to add a new flow log enter name, direction, action, target s3 bucket, and select + flow log to complete the configuration of the flow log it becomes applied once you provision your changes ipv4 configuration this field is automatically populated if dynamic host configuration protocol (dhcp) is enabled, the internet protocol version 4 (ipv4) address is dynamic, meaning it can change while the vcpu server is operational or in the case of a restart add additional public ip addresses in add ip it is an optional field ipv6 configuration you can populate a nic ipv6 cidr block with prefix length /80 or allow it to be automatically assigned from the vdcs allocated range, as seen in the screenshot below add additional public ip addresses in add ip it is an optional field select provision changes result ipv6 is enabled for the selected server note ipv6 cidr assigned to lans(/64) and nics(/80 and /128) must be unique you can create a maximum of 256 ipv6 enabled lans per vdc
