 - interval: the host will be pinged every "interval" seconds.
 - ping-protocol: indicates which protocol to use to ping the destination host,
   the currently supported protocols are TCP (tcp, tcp_ipv6) and ICMP (icmp, icmpv6).
+  This configuration can be used to perform a protocol fallback, in which N pings
+  are performed with one protocol, and then after those N attempts, a second protocol
+  is used. For example, with the given configuration:
+    ping-protocol=ICMPv6,42,ICMP
+  the program will ping a host 42 times using the ICMP over IPv6, and then it will
+  use the ICMP over IPv4 after those 42 attempts.

 - QoS-Flags of the ping packets should be configurable.
 
 - Make the configuration file reloadable (see bpdyndns).
