Hej


 AÖ>  Vet inte, jag använder bara v4. Vad är ändrat till v6?

=======================
* Expanded Addressing Capabilities
IPv6 increases the IP address size from 32 bits
to 128 bits, to support more levels of addressing hierarchy, a much greater
number of addressable nodes, and simpler auto-configuration of addresses. The
scalability of multicast routing is improved by adding a 'scope' field to
multicast addresses. And a new type of address called an 'anycast address' is
defined, used to send a packet to any one of a group of nodes.

* Header Format Simplification
Some IPv4 header fields have been dropped or made
optional, to reduce the common-case processing cost of packet handling and to
limit the bandwidth cost of the IPv6 header.

* Improved Support for Extensions and Options
Changes in the way IP header options
are encoded allows for more efficient forwarding, less stringent limits on the
length of options, and greater flexibility for introducing new options in the
future.

* Flow Labeling Capability
A new capability is added to enable the labeling of
packets belonging to particular traffic 'flows' for which the sender requests
special handling, such as non-default quality of service or 'real-time'
service.

* Authentication and Privacy Capabilities
Extensions to support authentication,
data integrity, and (optional) data confidentiality are specified for IPv6.
