Automatically configures IPv6 network interfaces at boot time.
autoconf6 [ - v] [ - 6 ] [ interface_name ]
The autoconf6 command is used at boot time to assign addresses to network interfaces and add some needed routes. It configures the link-local address, adds the appropriate interface route, as well as adds a compatibility address if an IPv4 address exists. autoconf6 should be used after configuration of IPv4 and before any IPv6 action.
|- v||Verbose output. The program displays what it is doing and/or what it is failing.|
|- 6||Don't install the SIT tunnel interface. The SIT interface and IPv4-compatible interoperability are not installed.|
|interface_name||Give to the program the name of the main IEEE LAN interface.|
This is an example output from the - v flag:
