Dnsmasq 2.66 is now available from


The complete changelog wrt 2.65 is below.



version 2.66
             Add the ability to act as an authoritative DNS
             server. Dnsmasq can now answer queries from the wider 'net
             with local data, as long as the correct NS records are set
             up. Only local data is provided, to avoid creating an open
             DNS relay. Zone transfer is supported, to allow secondary
             servers to be configured.

             Add "constructed DHCP ranges" for DHCPv6. This is intended
             for IPv6 routers which get prefixes dynamically via prefix
             delegation. With suitable configuration, stateful DHCPv6
             and RA can happen automatically as prefixes are delegated
             and then deprecated, without having  to re-write the
             dnsmasq configuration file or restart the daemon. Thanks to
             Steven Barth for extensive testing and development work on
             this idea.

             Fix crash on startup on Solaris 11. Regression probably
             introduced in 2.61.  Thanks to Geoff Johnstone for the

             Add code to make behaviour for TCP DNS requests that same
             as for UDP requests, when a request arrives for an allowed
             address, but via a banned interface. This change is only
             active on Linux, since the relevant API is missing (AFAIK)
             on other platforms. Many thanks to Tomas Hozza for
             spotting the problem, and doing invaluable discovery of
             the obscure and undocumented API required for the solution.

             Don't send the default DHCP option advertising dnsmasq as
             the local DNS server if dnsmasq is configured to not act
             as DNS server, or it's configured to a non-standard port.

             DNSMASQ_REMOTE_ID variables to the environment of the
             lease-change script (and the corresponding Lua). These hold
             information inserted into the DHCP request by a DHCP relay
             agent. Thanks to Lakefield Communications for providing a
             bounty for this addition.

             Fixed crash, introduced in 2.64, whilst handling DHCPv6
             information-requests with some common configurations.
             Thanks to Robert M. Albrecht for the bug report and
             chasing the problem.

             Add --ipset option. Thanks to Jason A. Donenfeld for the

             Don't erroneously reject some option names in --dhcp-match
             options. Thanks to Benedikt Hochstrasser for the bug report.

             Allow a trailing '*' wildcard in all interface-name
             configurations. Thanks to Christian Parpart for the patch.

             Handle the situation where libc headers define
             SO_REUSEPORT, but the kernel in use doesn't, to cope with
             the introduction of this option to Linux. Thanks to Rich
             Felker for the bug report.

             Update Polish translation. Thanks to Jan Psota.

             Fix crash if the configured DHCP lease limit is
             reached. Regression occurred in 2.61. Thanks to Tsachi for
             the bug report.

             Update the French translation. Thanks to Gildas le Nadan.
