IPv6: The New Internet Protocol
dress, even though multiple devices are operated in the
home network. This restriction is no longer required with
IPv6. In the IPv6 range the provider assigns not just a
single address, but an entire subnet containing at least
2
64
addresses. This means that every station in the
home network can also receive a globally valid IP ad-
dress. It also simplifies many of the configuration issues
raised with NAT. The address of the subnetwork as-
signed by the provider is called a prefix. The provider as-
signs the prefix via DHCPv6 prefix delegation.
•
IPv4 addresses generally have to be configured manual-
ly or via DHCP (Dynamic Host Configuration Protocol).
IPv6 provides for a simpler and more automated configu-
ration of network devices.
IPv6 Addresses
This means that IPv6 makes approximately 340 sextillion
(around 3.4 x 10
38
) IPv6 addresses available. By compari-
son, the IPv4 address space has just over four billion IP ad-
dresses.
The Structure and Notation of IPv6 Addresses
•
Length of an IPv6 address: 128 bits
•
Structure of IPv6 addresses: division into eight blocks of
16 bits each
•
Notation of IPv6 addresses: hexadecimal format, with
the individual blocks separated from each other by co-
lons
•
Example of an IPv6 address:
fedc:ba98:7654:3210:fedc:ba98:7654:3210
•
Leading zeros within a block can be left out.
