-   out creating sockets for some interfaces depending on the
-   --interface, --address and --except-interface flags.  The
-   disadvantage of this approach is that it breaks if interfaces don't
-   exist or are not configured when the daemon starts and does the
-   socket creation step. In a hotplug-aware world this is a real
-   problem.
 
-   The alternative approach is to have only one socket, which is bound
+   The three modes are "wildcard", "bind-interfaces" and "bind-dynamic".
-   to the correct port and the wildcard IP address (0.0.0.0). That
-   socket will receive _all_ packets sent to port 53, no matter what
-   destination address they have. This solves the problem of
-   interfaces which are created or reconfigured after daemon
-   start-up. To make this work is more complicated because of the
-   "reply source address" problem. When a UDP packet is sent by a
-   socket bound to 0.0.0.0 its source address will be set to the
-   address of one of the machine's interfaces, but which one is not
-   determined and can vary depending on the OS being run. To get round
-   this it is neccessary to use a scary advanced API to determine the
-   address to which a query was sent, and force that to be the source
-   address in the reply. For IPv4 this stuff in non-portable and quite
-   often not even available (It's different between FreeBSD 5.x and
-   Linux, for instance, and FreeBSD 4.x, Linux 2.0.x and OpenBSD don't
-   have it at all.) Hence "bind-interfaces" has to always be available
-   as a fall back. For IPv6 the API is standard and universally
-   available.
 
-   It could be argued that if the --interface or --address flags are
+   In "wildcard" mode, dnsmasq binds the wildcard IP address (0.0.0.0 or
-   used then binding interfaces is more appropriate, but using
+   ::). This allows it to recieve all the packets sent to the server on
-   wildcard binding means that dnsmasq will quite happily start up
+   the relevant port. Access control (--interface, --except-interface,
-   after being told to use interfaces which don't exist, but which are
+   --listen-address, etc) is implemented by dnsmasq: it queries the
-   created later. Wildcard binding breaks the scenario when dnsmasq is
+   kernel to determine the interface on which a packet was recieved and
-   listening on one interface and another server (most probably BIND)
+   the address to which it was sent, and applies the configured
-   is listening on another. It's not possible for BIND to bind to an
+   rules. Wildcard mode is the default if neither of the other modes are
-   (address,port) pair when dnsmasq has bound (wildcard,port), hence
+   specified. 
-   the ability to explicitly turn off wildcard binding.
+
+   In "bind-interfaces" mode, dnsmasq runs through all the network
+   interfaces available when it starts, finds the set of IP addresses on
+   those interfaces, filters that set using the access control
+   configuration, and then binds the set of IP addresses. Only packets
+   sent to the allowed addresses are delivered by the kernel to dnsmasq.
+
+   In "bind-dynamic" mode, access control filtering is done both by
+   binding individual IP addresses, as for bind-interfaces, and by
+   inspecting individual packets on arrival as for wildcard mode. In
+   addition, dnsmasq notices when new interfaces appear or new addresses
+   appear on existing interfaces, and the resulting IP addresses are
+   bound automatically without having to restart dnsmasq.
+
+   The mode chosen has four different effects: co-existence with other
+   servers, semantics of --interface access control, effect of new
+   interfaces, and legality of --interface specifications for
+   non-existent inferfaces. We will deal with these in order.
+
+   A dnsmasq instance running in wildcard mode precludes a machine from
+   running a second instance of dnsmasq or any other DNS, TFTP or DHCP
+   server. Attempts to do so will fail with an "address in use" error. 
+   Dnsmasq running in --bind-interfaces or bind-dynamic mode allow other
+   instances of dnsmasq or other servers, as long as no two servers are
+   configured to listen on the same interface address. 
+
+   The semantics of --interface varies subtly between wildcard or
+   bind-dynamic mode and bind-interfaces mode. The situation where this
+   matters is a request which arrives via one interface (A), but with a
+   destination address of a second interface (B) and when dnsmasq is
+   configured to listen only on B. In wildcard or bind-dynamic mode, such
+   a request will be ignored, in bind-interfaces mode, it will be
+   accepted.
+
+   The creation of new network interfaces after dnsmasq starts is ignored
+   by dnsmasq when in --bind-interfaces mode. In wildcard or bind-dynamic
+   mode, such interfaces are handled normally.
+
+   A --interface specification for a non-existent interface is a fatal
+   error at start-up when in --bind-interfaces mode, by just generates a
+   warning in wildcard or bind-dynamic mode.
 
 Q: Why doesn't Kerberos work/why can't I get sensible answers to
    queries for SRV records.
