## NAME
       ifcfg - simplistic script which replaces ifconfig IP management

## SYNOPSIS
       **ifcfg** [ _DEVICE_ ] [ _command_ ] _ADDRESS_ [ _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.


## 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.


## NOTES
       This script is not suitable for use with IPv6.
