[GTER] Implantação de IPV6

(não achei em português)

The first thing that should be mentioned about IPv6 subnetting is that a
different *mode of thought* is called for. In IPv4 you usually think about
how many *addresses* you have available and how you can allocate enough of
them to each end user. In IPv6 you usually think about how many (/64)
*subnets* you have available and how you can allocate them to end users.
You almost never worry about how many IP addresses will be used in a given
subnet. Except for some special cases like point to point links, each
subnet just simply has way more addresses available than it will ever
require, so instead you worry only about allocating subnets, not hosts
inside them.

*IPv6 subnets are usually /64 because that is required in order for SLAAC
<http://tools.ietf.org/html/rfc4862> (stateless address autoconfiguration)
to work. *Even where SLAAC is not in use, there may be other reasons to use
/64. For example, there might be some end user devices out there that just
assume /64, or else routing subnets longer than /64 might be inefficient on
some routers because the router implementor has optimized the case of /64
or shorter routes in order to save routing table memory.
