The main technique being to omit repetitive 0’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 4’s giving 8 groups or blocks. See Binary numbers explainedīecause 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 addressesĪn 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. įor small business/home and home office networks it is likely to be many years before IPV6 becomes an issue.Īll 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.Īlthough it has been around almost 10 years it is still not widely deployed and supported.
