Take the part before the underscore and check:

	% whatis ip6addrctl
	ip6addrctl(8) - configure address selection policy for IPv6 and IPv

Then see "man 8 ip6addrctl" for details:

NAME
     ip6addrctl - configure address selection policy for IPv6 and IPv4

[...]

DESCRIPTION
     The ip6addrctl utility manages the policy table of source and destination
     address selection for outgoing IPv4 and IPv6 packets.  When ip6addrctl is
     invoked without an argument or with a single argument show, it prints the
     content of the policy table currently installed in the kernel.

[...]

HISTORY
     The ip6addrctl utility first appeared in the KAME IPv6 protocol stack
     kit.  The original command name was addrselect, but it was then renamed
     to the current one so that the name would describe its function well.



The manual page dating says "September 25, 2001", so it's not
exactly new. ;-)
