version 2.61
Re-write interface discovery code on *BSD to use
getifaddrs. This is more portable, more straightforward,
and allows us to find the prefix length for IPv6
addresses.
Add ra-names DHCPv6 keyword which adds AAAA records
for dual-stack hosts which get IPv6 addresses via SLAAC.
Add ra-names, ra-stateless and slaac keywords for DHCPv6.
Dnsmasq can now synthesise AAAA records for dual-stack
hosts which get IPv6 addresses via SLAAC. It is also now
possible to use SLAAC and stateless DHCPv6, and to
tell clients to use SLAAC addresses as well as DHCP ones.
Thanks to Dave Taht for help with this.
Add --dhcp-duid to allow DUID-EN uids to be used.
Explicity send DHCPv6 replies to the correct port, instead
of relying on clients to send requests with the correct
source address, since at least one client in the wild gets

Don't cache data from non-recursive nameservers, since it
may erroneously look like a valid CNAME to a non-exitant

Call SO_BINDTODEVICE on the DHCP socket(s) when doing DHCP
on exactly one interface and --bind-interfaces is set. This
makes the OpenStack use-case of one dnsmasq per virtual

Les bits "managed address" sont positionnés, sauf pour un dhcp-range marqué
comme "ra-only" (annonce routeur uniquement). Dans ce cas le service d'annonce
routeur est rendu mais aucun service DHCPv6 n'est assuré, et les bits "managed
address" ne sont pas positionnés.
Par défaut, les bits "managed address" sont positionnés, et le bit "use SLAAC"
("utiliser SLAAC") est réinitialisé. Cela peut-être changé pour des
sous-réseaux donnés par le biais du mot clef de mode décris dans
.B --dhcp-range.
Les paramètres DNS du RFC6106 sont inclus dans les annonces. Par défaut,
l'adresse link-local appropriée parmi celles de la machine sur laquelle tourne

options dns-server et domain-search sont utilisées respectivement pour RDNSS et
