# IPv6 Privacy Extensions (RFC 4941)
# ---
# IPv6 typically uses a device's MAC address when choosing an IPv6 address
# to use in autoconfiguration. Privacy extensions allow using a randomly
# generated IPv6 address, which increases privacy.
#
# Acceptable values:
# 0 - don’t use privacy extensions.
# 1 - generate privacy addresses
# 2 - prefer privacy addresses and use them over the normal addresses.
