Global addresses are routable on the internet and start with 2001:

Link Local вЂ“ Scope network link- Not Routed internally or externally.

Unique Local - Scope Internal Network or VPN internally routable, but Not routed on Internet.

Global Unicast Address вЂ“Scope Internet- routed on Internet.

The upper 48 bits are used for the global network addresses and are for routing over the internet.

If we look at the upper 64 bits in more detail we can see that it is split into 2 blocks of 48 and 16 bits respectively the lower 16 bits are used for subnets on an internal networks, and are controlled by a network administrator. See this Wiki description for exact details. The lower 64 bits identify the address of the interface or node, and is derived from the actual physical or MAC address using IEEEвЂ™s Extended Unique Identifier (EUI-64) format.

The address is split into 2 64 bit segments the top 64 bits is the network part and the lower 64 bits the node part: The first step is to split the address into two parts. This was done initially using Address classes and later using subnet masking. In IPv4 an address is split into two components a network component and a node component. The main technique being to omit repetitive 0вЂ™s as shown in the example above. Note: Because of the length of IPv6 addresses various shortening techniques are employed. The groups are written with a : (colon) as a separator. These numbers are grouped in 4вЂ™s giving 8 groups or blocks. See Binary numbers explainedД«ecause an hexadecimal number uses 4 bits this means that an IPv6 address consists of 32 hexadecimal numbers. IPv6 addresses are written using hexadecimal, as opposed to dotted decimal in IPv4. Therefore it will help if you are already familiar with IPv4 -See IPv4 Addressing and classes for Beginners IPv6 addressesДЄn Ipv6 address uses 128 bits as opposed to 32 bits in IPv4.

In this tutorial I want to take a quick look at IPv6 addresses, and how they relate to IPv4 addresses. ДЇor small business/home and home office networks it is likely to be many years before IPV6 becomes an issue.ДЄll modern computers and mobile phones support both IPv4 and IPv6, and if you look at your device IP addresses you will probably see both. However adoption rates are increasing rapidly and IPv6 traffic crossed the 10% threshold in February 2016 ( wiki). IPV6 has been developed to replace IPV4 which is running out of addresses.ДЄlthough it has been around almost 10 years it is still not widely deployed and supported.
