"&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."
