IPv6 addresses are structured differently from IPv4 address-

IP masquerading
IP masquerading is a technique used within IPv4 networks.
With IP masquerading a computer or LAN can be protected
from unauthorized connection requests from the Internet.
Masquerading works by converting the IP addresses used in a
network to one public IP address. From the outside it appears
as if all requests are sent from a single computer.
IP network
A network in which data exchange takes place on the basis of
the Internet Protocol (IP) is called an IP network.
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 In-
ternet, and local memory expanded by adding online storage.
NAT
short for Network Address Translation
NAT is a technique used within IPv4 networks. NAT is used in
routers to replace the address information in data packets
with new address information. A typical application for NAT is
routers that connect local networks with the Internet. In local
networks, every network device has a private IP address,
