From: "TJ" <trejrco () gmail com>As a general rule, most clients are following the "If we gave them static IPv4 addresses we will give them static IPv6 addresses" (infrastructure, servers, etc). The whole SLAAC(autoconfig) vs DHCPv6 is a separate (albeitrelated) conversation ... ----------------------------------------------------I'm still an IPv6 wussie and would like to learn more before moving forward, so would anyone care to share info on experiences with this decision?
Here's some pro's and con's to both SLAAC: - widely implemented in host v6 stacks that have shipped - widely implemented on v6 routers - really, really, really broken: it didn't support handing out any DNS info until RFC 5006, thus SLAAC still requires human intervention on a client to make "teh v6 interwebs" work. It will probably be a painful wait until 5006 gets more widely implemented on hosts (if ever, for some) & routers. - probably "faster" than dhcpv6 w/ tuning timers. Could be better for mobile thingys. - supports RFC 3041 "security by obscurity" extensions. DHCPv6 - doesn't ship w/ some OS's - new (danger code), not all features implemented - router support for dhcpv6 relay very limited - advanced things like prefix delegation don't really seem to have been ironed out. In case you weren't confused enough between the two, they are not mutually exclusive. You can run both SLAAC and DHCPv6 at the same time on the same L2.
