ping6
sends ICMPv6 echo requests to IPv6 hosts
TLDR
Ping IPv6 address
SYNOPSIS
ping6 [-c count] [-i interval] [-s size] [-I interface] [options] destination
DESCRIPTION
ping6 sends ICMPv6 echo requests to IPv6 hosts. It tests network connectivity and measures latency.
Link-local addresses require interface specification. The -I option binds to specific network interface.
Statistics show packet loss and round-trip times. Minimum, average, and maximum latency are reported.
Flood mode tests network under load. Requires root privileges.
Many systems now use ping for both IPv4 and IPv6. The separate ping6 command remains for compatibility.
PARAMETERS
-c COUNT
Stop after count packets.-i INTERVAL
Seconds between packets.-s SIZE
Packet data size.-I INTERFACE
Source interface.-q
Quiet output.-f
Flood mode.-t TTL
Time to live.-w DEADLINE
Timeout in seconds.
CAVEATS
Firewalls may block ICMPv6. Link-local requires interface. Flood ping requires root.
HISTORY
ping6 appeared with IPv6 implementations in the 1990s. On many modern systems, the ping command handles both protocols, making ping6 a compatibility alias.
