IPv6: A Better Way to Move Data Around

IPv6 introduced great enhancements to IPv4. The improvements include Mobility, security, smaller header, address formatting.

Mobility is a new, IPv6 feature. Mobility allows users with mobile network devices to change locations around the network. Mobile IP is an IETF standard that is available for IPv4 as well as IPv6. This standard permits mobile devices to move without disruptions in established networks.

IPSec is another IETF standard for IP network security. It is offered by both protocols. The IP net security characteristics are similar in both environments. IPSec is improved in IPv6 and can be enabled on every node that uses this protocol.

Smaller Header

The header used for IPv6 improves routing efficiency by decreasing the number of records in the routing tables. No broadcasts are produced by IPv6. IPv4 creates broadcasts that generate a high level of network traffic. This network traffic produces an event known as a broadcast storm and the whole network stops functioning. IPv6 replaced broadcast traffic with multicast and anycast traffic.

Address Formatting

The hexadecimal digits A, B, C, D, E, and F represented in IPv6 addresses are not case-sensitive. The IPv6 address string format is not fixed. The next rules are used for IPv6 address string notations: The first 0s in a field are optional. For example 09C0 equals 9C0 and 0000 equals 0. One or more sets of 0s can be deleted and replaced with “::”. Also, only one “::” is permitted in an address.

The “::” symbolization greatly shrinks the size of most … Read the rest >>>>
