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.
     However, 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
