I wish I knew why I set them to 2. :-/. If I _wanted_ them set to 1, then I
could use the knob in rc.conf. I know I have some complaints about the privacy
things being done with MAC address and IPv6 addresses, because I need my IPv6
addresses to be predictable for DNS. Trying to figure out how to get (1)
[information] secure and (2) predictable/repeatable addresses so I can set up
forward and reverse DNS has been challenging….
Though, mostly that’s an issue for the client machines on the network, not the
router. The router mostly has hard-set IPv6 addresses, since it is after all,
a router. Maybe I was trying to adjust in some way the upstream to my ISP.
There isn’t any SLACC going on on my router at the moment though, I don’t
think, so this may be some left-over from my trials and tribulations last year
getting the IPv6 allocation from Verizon up and running.
So, no-one knows any reason why these numbers being “2” could mean anything?
If so I’ll pull that out of my config.
