I basically don't care about the privacy aspect for now (it is more of a lab setup, and my IPv4 address is static, and its PTR resolves to something with my surname in it ;). At least at the moment I would prefer shorter IPv6 addresses than can be constructed from the MAC, even considering the possibility to "fake" the MAC to something with many zeroes, using historic/obsolete MAC vendor ids with zeroes in them etc., because identifying IPs at one glance seems very attractive to me. Right now I want as short/as memorable IPv6 addresses as possible. > Use the NetworkManager to configure that. > Automatic means using SLAAC (if available in the RA) and DHCPv6 (if > available in the RA).

What is the suggested way to make this survive a reboot in Debian? Thanks for your comprehensive reply! /ralph
