PREFIX(8)		FreeBSD	System Manager's Manual		     PREFIX(8)

NAME
     prefix -- configure network interface prefixes

SYNOPSIS
     prefix interface prefix [set | delete]

DESCRIPTION
     prefix is used to assign an prefix	to a network interface.	 This command
     is	currently just a frontend of ifconfig(8), and is not recommended to be
     used.

SEE ALSO
     netstat(1), netintro(4), ifconfig(8), rc(8)

HISTORY
     The prefix	command	first appeared in WIDE/KAME IPv6 protocol stack	kit.
     Previously, this command was used to manipulate prefixes separately from
     interface identifiers, intending to be used for prefix renumbering.  How-
     ever, it had been known that the manipulation mechanism was not friendly
     with traditional address management engine	in the kernel.	Thus, the KAME
     developers	decided	to invalidate the prefix manipulation mechanism, and
     to	clarify	the entire address/prefix manipulation in February 2001.
     Since then, this command has almost been obsoleted.  All users should now
     use ifconfig(8).

     IPv6 and IPsec support based on the KAME Project (http://www.kame.net/)
     stack was initially integrated into FreeBSD 4.0
