in Linux guests, these are controlled via these two ``sysctl`` variables:
- ``net.ipv6.conf.*.use_tempaddr`` (Privacy Extensions)
- ``net.ipv6.conf.*.addr_gen_mode`` (link-local and autoconf address generation)
Both of these settings should be disabled (zero).
This allows the use of non-changing interface identifiers for IPv6 addresses
according to RFC3041 semantics. It should be disabled (zero) so that stateless
addresses are constructed using a stable, EUI64-based value.
- ``net.ipv6.conf.*.addr_gen_mode``
This defines how link-local and auto-configured IPv6 addresses are
generated. It should be set to zero (default) so that IPv6
addresses are generated using an EUI64-based value.
.. note::
Support for ``addr_gen_mode`` was added in kernel version 4.11.
Other types of guests might have similar configuration options, please
consult your distribution documentation for more information.
