|
|
The
|
|
.Nm
|
|
utility is used to assign a prefix
|
|
to a network interface.
|
|
This command is currently just a frontend of
|
|
.Xr ifconfig 8 ,
|
|
and is not recommended to be used.
|
|
.Sh SEE ALSO
|
|
.Xr netstat 1 ,

.Xr rc 8
|
|
.Sh HISTORY
|
|
The
|
|
.Nm
|
|
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.
|
|
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
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
IPv6 and IPsec support based on the KAME Project (http://www.kame.net/) stack
|
|
was initially integrated into
|
|
.Fx 4.0
