+IPv6 support
+------------
+You can can compile fping with support for IPv6 addresses. A separate binary
+is used for that, called fping6. To build it, use ./configure --enable-ipv6
+(possibly combined with --enable-ipv4 to also build fping for IPv4). E.g.:
+
+  # ./configure --prefix=/usr/local --enable-ipv4 --enable-ipv6
+  # make
+  # make install
+  # sudo setcap cap_net_raw+ep /usr/local/bin/fping*
