msgid "&PRODUCT;supports Internet Protocol version 6 (IPv6), the recent version of the Internet Protocol (IP) that defines routing the network traffic. IPv6 uses a 128-bit address that exponentially expands the current address space that is available to the users. IPv6 addresses consist of eight groups of four hexadecimal digits separated by colons, for example, 5001:0dt8:83a3:1012:1000:8s2e:0870:7454. &PRODUCT; supports IPv6 for public IPs in shared networks. With IPv6 support, VMs in shared networks can obtain both IPv4 and IPv6 addresses from the DHCP server. You can deploy VMs either in a IPv6 or IPv4 network, or in a dual network environment. If IPv6 network is used, the VM generates a link-local IPv6 address by itself, and receives a stateful IPv6 address from the DHCPv6 server."
