for details. Instead, the keyword
.B ra-names
may be used. This does the same at ra-only, but also enables a mode
which gives DNS names to dual-stack hosts which do SLAAC for
IPv6. Dnsmasq uses the hosts IPv4 lease to derive the name, network
segment and MAC address and assumes that the host will also have an
IPv6 address calculated using the SLAAC alogrithm, on the same network
segment. An AAAA record is added to the DNS for this IPv6
address. Note that this is only happens for directly-connected
networks, (not one doing DHCP via a relay) and it will generate an
erroneous AAAA record if a host is using privacy extensions or does
not support IPv6. Use with care.
The interface:<interface name> section is not normally used. See the
NOTES section for details of this.
