ipv6pref -- set IPv6 address selection preference

## SYNOPSIS

**ipv6pref** \[**-p** \| **-t**\] *\<cmd\>*

**v6pub** *\<cmd\>*

**v6tmp** *\<cmd\>*

## DESCRIPTION

This program is a wrapper script that preloads the ipv6pref library, allowing the user to select its preference for the IPv6 address selection. It is usually called using the symlinks **v6pub** or **v6tmp** that advice the supplied command to use either the public IPv6 address for outgoing connections or the temporary address assigned when using the IPv6 Privacy Extensions.

## OPTIONS

- **-p**

  Instruct the called program to use the public IPv6 address for outgoing connections. This is the default if the wrapper is called by the name **v6pub**.

- **-t**

  Instruct the called program to use the temporary, randomly generated IPv6 addresses for outgoing connections. This is the default if the wrapper is called by the name **v6tmp**.
