+    <address> is the IPv4 address of the default server. Alternatively, a
+              resolvable hostname is supported, but this name will be resolved
+              during start-up.
+
+    <ports>   is a mandatory port specification. All connections will be sent
+              to this port, and it is not permitted to use port offsets as is
+              possible with normal servers.
+
+  The "disabled" keyword designates a default server for use when no other
+  server can take the connection. In the past it was used to forward non
+  persistent connections to an auxiliary load balancer. Due to its simple
+  syntax, it has also been used for simple TCP relays. It is recommended not to
+  use it for more clarity, and to use the "server" directive instead.
