public int temp_preferred_lifetime { get; set; }
The preferred lifetime of autogenerated temporary addresses, in seconds.
Having a per-connection setting set to "0" (default) means fallback to global configuration "ipv6.temp-preferred-lifetime" setting". If it's also unspecified or set to "0", fallback to read "/proc/sys/net/ipv6/conf/default/temp_prefered_lft".
