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


NAME

     prefix -- configure network interface prefixes


SYNOPSIS

     prefix interface prefix [set | delete]


DESCRIPTION

     The prefix utility is used to assign a prefix to a network interface.
     This command is currently just a frontend of ifconfig(8), and is not rec-
     ommended to be used.


SEE ALSO

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


HISTORY

     The prefix utility 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
