# 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. net.ipv6.conf.all.use_tempaddr = 2 net.ipv6.conf.default.use_tempaddr = 2
