I know many people think they know what IPv6 is. But 99% of the articles are talking about IPv6 from a global address space. I want you to _ignore_ all those discussions.
I will ask people to read up on IPv6, how it works on the same, physical layer-2 network (no routing). How ARP and DHCP are eliminated, how systems and equipment differ, etc... from IPv4. Also understand how many distros, SuSE is the one I've personally run into (Ubuntu was also mentioned), ship with the LINKLOCAL IPv6 enabled. That's not used for _any_ routing at all, just local layer-2 traffic. Because IPv6 co-exists with IPv4, but as a sysadmin, you need to know about it. Most don't. Most wonder why they have issues, not realizing there is an IPv6 LINKLOCAL address on their eth0. Again, I'm only stating that on the LPIC-1 for 2007+, based on _now_, people need to know what an IPv6 looks like, and how to disable it on eth0 (without just doing "ifconfig eth0 down" ;-). If you're adventureous, then start reading up on how IPv6 can be used for internal routes. These IPv6 addresses are _unique_ from both the LINKLOCAL _and_ the global address space. At the most, this is what a sysadmin would configure via "ifconfig" and "route" (static) when there are more than one subnet. And that's only what I was saying we might want to see on the LPIC-2. The sooner we make IPv6 considerations more ubiquitous with IPv4 considerations, the more people will not see the difference in consideration. After all, I don't know how many times I've seen people freak when they seen IPv6 addresses in a /etc/hosts file, a DHCP block or DNS zones. -- Bryan J.
