ipv6-slaac-logger - accountability for SLAAC addresses with RFC 9686

One of the most common objections I hear to SLAAC, and frankly one of the most legitimate ones, is accountability. “If the host picks its own address, how do I know who had 3fff:db8:10::5c1e:9aff:fe3b:21aa last Tuesday at 21:00?” With DHCPv6 IA_NA you get a lease log - this is what everyone is used to with legacy IP - and why so many enterprises ask for DHCPv6 support. With SLAAC, and especially with temporary/privacy addresses rotating underneath you, you get… whatever you can scrape out of neighbor caches before they age out.

IPB 210 - IPv6-Mostly Is Really Dual-Stack

IPv6-mostly is a foothold to get from your dual-stack network to a much more predominantly IPv6-run network, but the reality is that IPv6-mostly has a whole set of dependencies about the fact that IPv4 exists on the network. Ed, Nick and Tom discuss the realities of IPv6-mostly networks such as DHCP and SLAAC configurations, VPN interactions, and how new tools like Windows CLAT can help transition to full IPv6 adoption.
