Disable the loopback for multicasts, so the transmitting host doesn't see the ICMP requests. If preload is specified, ping6 sends that many packets as fast as possible before falling into its normal mode of behavior. Numeric output only. No attempt will be made to lookup symbolic names for host addresses. This is useful for diagnosing data-dependent problems in a network.
Nothing is displayed except the summary lines at startup time and when finished.
Bypass the normal routing tables and send directly to a host on an attached network. If the host is not on a directly-attached network, an error is returned. The default is 56, which translates into 64 ICMPv6 data bytes when combined with the 8 bytes of ICMPv6 header data. The default is 10. When using ping6 for fault isolation, it should first be run on the local host, to verify that the local network interface is up and running.
