Glossary
IPv4 addresses are 32 bits long, such that IPv4 offers an ad-
dress space of 2
32
IP addresses, or just over four billion. The
latest estimates suggest that the last IPv4 addresses will be
assigned by the beginning of 2012.
The successor protocol to IPv4 is IPv6.
IPv6
short for Internet Protocol version 6
The successor protocol to IPv6 is IPv4.
IPv6 addresses are 128 bits long. This means that IPv6 makes
approximately 340 undecillion (~ 3.4 x 10
36
) IPv6 addresses
available. Each private user can be allotted over 18 quintil-
lion public IPv6 addresses from her or his Internet Service
Provider.
The dearth of addresses in IPv4 is only one of the reasons for
introducing IPv6. IPv6 also offers additional advantageous
characteristics in the framework of communication within IP
networks.
NAS functionality
NAS is short for Network Attached Storage
NAS designates one or more devices that are integrated into a
network to provide storage space.
In connection with the FRITZ!Box, NAS functionality means
that various services for connected USB storage media are
available in the FRITZ!Box so that it easier for you to use your
data and make them available in the local network. It is easy
to exchange documents in the local network via the storage
medium on the FRITZ!Box. The media server makes music, im-
ages and videos in the network available to compatible play-
back devices. Files can also be released for sharing in the
Internet, and local memory expanded by adding online
storage.
