Description Andy Smith 2010-05-12 17:00:13 UTC
I believe it would be useful to make some mention of the fact ping6 is required to  ping IPv6 IP addresses in the IPv6 section of the handbook:

http://www.freebsd.org/doc/en/books/handbook/network-ipv6.html

Also might be worth mentioning nslookup by default will not search for AAAA records (yep I know its deprecated but bet its still used more often than any other DNS lookup tool).
Id say these are worth mentioning as other OSs don´t necessarily behave the same way and this can be confusing for those who have to manage multiple OSs. IE solaris doesnt have a ping6 command, but Linux does etc....

thanks Andy.

There's a single binary: 

% ls -i /sbin/ping
3749407 /sbin/ping
% ls -i /sbin/ping6
3749407 /sbin/ping6
% 

<https://docs.freebsd.org/en/books/handbook/advanced-networking/#_troubleshooting> refers to 
<https://www.freebsd.org/cgi/man.cgi?query=ping&sektion=8&format=html> for ping(8). 

From <https://www.freebsd.org/cgi/man.cgi?query=ping&sektion=8&manpath=FreeBSD#DESCRIPTION>: 

> … the specific IP versioncan be requested by -4 or -6 options, respectively. 
> For backwards-compatibility, ICMPv6 can also be selected by invoking 
> the binary as ping6. …

(In reply to Graham Perrin from comment #2)

Noting they're still separate in 12.x.
[pauamma@gadfly] ~% ls -li /sbin/ping*
657235 -r-sr-xr-x  1 root  wheel  32552 Feb  9  2021 /sbin/ping
657237 -r-sr-xr-x  1 root  wheel  41456 Feb  9  2021 /sbin/ping6

I'm gonna close this since ping supports IPv6.
I put overcome by events, maybe not the best status.
