+# Do Router Advertisements, BUT NOT DHCP for this subnet, also try and
+# add names to the DNS for the IPv6 address of SLAAC-configured dual-stack
+# hosts. Use the DHCPv4 lease to derive the name, network segment and
+# MAC address and assume that the host will also have an
+# IPv6 address calculated using the SLAAC alogrithm.
+# This will generate an erroneous AAAA record if a host is using privacy
+# extensions or does not support IPv6. Use with care.
