IPv6 addresses are now currently used.

The ability to identify a user will easier by IPv6.

You can use a IPv6 anonymizer or do the following.

-

In a Linux Mint system, the privacy extensions can be an entry in the file
/etc/sysctl.conf turn on. You just have to add the following lines:

/etc/sysctl.conf:
net.ipv6.conf.all.use_tempaddr = 2
net.ipv6.conf.default.use_tempaddr = 2

After restart of the network components, the result can be checked on an IPv6 network using the following command: ip -6 addr show

~ $ ip -6 addr show
1: lo:  mtu 16436
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
3: wlan0:  mtu 1500 qlen 1000
inet6 2001:6f8:9a9:0:449f:8124:2f5b:ab63/64 scope global temporary dynamic
valid_lft 85989sec preferred_lft 13989sec
inet6 2001:6f8:9a9:0:221:6aff:fe0d:a884/64 scope global dynamic
valid_lft 85989sec preferred_lft 13989sec
inet6 fe80::221:6aff:fe0d:a884/64 scope link
valid_lft forever preferred_lft forever

A made ​​by the previously adjustment created second IPv6 address contains no longer parts of the MAC address of the network interface, but a randomly generated value and the attribute 'temporary' (instead of 'forever').
