 .Nm Prefix
 is used to assign an prefix
 to a network interface and/or renumbering
 network interface prefixes.
-.Nm Prefix

 must be used at boot time to define the network prefix
 of each interface present on a machine; it may also be used at
 a later time to renumbering multiple interface's prefixes
 and other prefix related parameters.
