Release IPv6 address

Command Description
Release [ -x] <Interface 1> ... <Interface n> The DHCPv6 client returns its IPv6 address and/or its prefix to the DHCPv6 server. It then submits a new request for an address or prefix to the DHCPv6 server. Depending on the provider, the server assigns a new address to the client, or reassigns the previous one. Whether the client receives a different address or prefix is determined solely by the server. The option switch -x suppresses the confirmation message. The * wildcard applies the command on all of the interfaces and prefix delegations.
