One of the biggest advantages of IPv6 is the ease of renumbering thanks to SLAAC and DHCPv6. Easy renumbering of IPv6 addresses should, in theory, make some privacy protection methods easy to implement. Here's how it works, and and how it doesn't solve all privacy problems.

Heavy Networking 673: Multicast DNS Gone Wild On Your WLAN
You know all those Apple and other IoT devices connected to your wireless network? Lots of them run apps that discover services on your network via multicast DNS (mDNS). All of that mDNS traffic can have a significant impact on your WLAN’s performance. On today's Heavy Networking we talk with guest Bryan Ward who has actually measured the impact of mDNS on a production wireless network to see what would happen if he let mDNS traffic run wild.
