# ifcfg(8)

simplistic script which replaces ifconfig IP management

## NAME

ifcfg - simplistic script which replaces ifconfig IP management

## SYNOPSIS

**ifcfg** \[ *DEVICE* \] \[ *command* \] *ADDRESS* \[ *PEER* \]

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.
