NAME
       ifcfg - simplistic script which replaces ifconfig IP managment

SYNOPSIS
       ifcfg [ DEVICE [ :ALIAS: ] ] [ command ] ADDRESS [ LENGTH ] [ PEER ]



DESCRIPTION
       This manual page documents briefly the ifcfg command.

       This is a simplistic script replacing one option of ifconfig , namely, IP address management. It not only adds addresses,
       but also carries out Duplicate Address Detection RFC-DHCP, sends unsolicited ARP to update the caches of other hosts
       sharing the interface, adds some control routes and restarts Router Discovery when it is necessary.

       I strongly recommend using it instead of ifconfig both on hosts and on routers.


IFCONFIG - COMMAND SYNTAX
       DEVICE - it may have alias, suffix, separated by colon.


       command
              - add, delete or stop.


       address
              - optionally followed by prefix length.


       peer   - optional peer address for pointpoint interfaces.


EXAMPLE
       This function determines, whether this is router or host.  It returns 0, if the host is apparently not router.
