# Description: dhcp6s provides IPv6 addresses and prefix assignment
#              administrative policy and configuration information for
#              DHCPv6 clients.  dhcp6s also manages those addresses and
#              prefixes, such as IPv6 addresses, prefixes, DNS server
#              addresses, or ntp server addresses.
