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.

Sonicwall – Old dog learns [some] new tricks

~12 years ago I had a drinking buddy that worked with me at the regional ISP. We had a lot in common, he had been an icon back in the didjits era of punk rock in Champaign Urbana and we had briefly been in a terrible band together. He introduced me to a dude that to this day I just knew as “Ravi Sonicwall”. He had apparently been recruited from the U of I, written a lot of the low level pieces of the original sonicwall and retired to enjoy life and buy beers (he actually scolded me at a bar for buying him a beer saying “when I’m in town, I buy the beers”).
