SYNOPSIS

    The ifconfig command assigns addresses to network interfaces. It
    also displays network interfaces and configures network interface
    parameters.

    For IPv4 environments, use the following syntax:

 ifconfig interface_id [address_family] [address[/bitmask] [dest_address]] [parameters]

    For IPv6 environments, use the following syntax:

 ifconfig interface_id address_family [[ip6prefix] address[/bitmask] [dest_address]] [parameters]

    To display information about interfaces, use the following
    syntaxes:

    ifconfig -a  [-d] [-u] [-v] [address_family]
    ifconfig -l  [-d] [-u] [-v] [address_family]
    ifconfig [-v] interface-id [address_family]
