IPv6 Configuration

You can enable the IPv6 LAN and configure the network to support IPv6. Using IPv6 LANs, devices can communicate on the same LAN using standard IPv6 protocols. IONOS LANs route packets between devices and networks, ensuring that the network runs smoothly and effectively.

Public IPv6 addresses

By default, every VDC is assigned a public /56 IPv6 CIDR block. You can choose to enable IPv6 in a LAN as per your needs and a maximum of 256 IPv6 enabled LANs can be created per VDC. On enabling IPv6 in a LAN, you can either select a /64 IPv6 CIDR block from the /56 IPv6 CIDR block assigned to the VDC or have a /64 block automatically assigned to the LAN. Public IPv6 addresses are assigned to both private and public LANs.

Each connected virtual NIC is then assigned a /80 IPv6 CIDR block and a single /128 IPv6 address, either automatically, or you can also select both. The /80 and /128 address must both be assigned from the /64 IPv6 CIDR block assigned to the corresponding LAN. DHCP assigns the first public IPv6 address and in total a maximum of 50 IPv6 addresses can be assigned per NIC. IPv6 addresses are static, meaning they remain assigned after a VM restart.

Prerequisites: Prior to enabling IPv6, make sure you have the appropriate privileges. New Virtual Data Center (VDC) can be created by the contract owners, administrators, or users with create VDC privilege. The leading number of bits in the address that cannot be changed is the prefix length. For Data Center IPv6 CIDR, the prefix length is /56.
