IPv6 has a few different modes, and only one requires no configuration,
but you don't even get nameservers in that case, so the connection is
pretty much good for local only.

If you want to actually *use* the IPv6 setup, then you need to either
statically configure nameservers, or you can use DHCP.  DHCP in IPv6
works in two modes, "lease" and "information-only".  In lease mode, DHCP
works exactly like in IPv4; a DHCP server is found and a lease obtained,
along with DHCP options just like IPv4.  In information-only mode, the
router advertisements (or static methods) provide the actual IPv6
address, but DHCP is additionally run, not to get a lease, but only to
retrieve DNS and other information.

In addition, static routes, search domains, etc can be used with IPv6.
Thus, IPv6 config will look a lot like IPv4.
