IPv4 and IPv6 (Term Paper Sample)


IPv4 and IPv6 will coexist over the next few years. Discuss the various protocols, tools and techniques used by administrators and ISPs to migrate their networks to IPv6. The word count is between 500 to 750 words.


IPv4 and ipv6
Internal protocol (IP) is the principal of digital rule for data exchange within two or more computers in a communication protocol. Internet protocol establishes internetworking through its routing mechanism. It defines packet structure then designs a modular data communication protocol as well as addressing datagram with a source server and destination server. There are current two version of IPS. The first version is the internet protocol version 4 (IPV4) and the latest version the internet protocol version 6 (IPV6). IPV4 version came to existence in 1981. The protocol accounts for most of today's internet traffic and operates by describing a network in which there is no quality of service guarantee. IPV4 use 32 bit addressing and allows 4,294,967,296 unique addresses. IPV4 was widely used in modern transmission control protocol. The version provides basic datagram delivery characteristics and it has been highly rated by users for more than 10 years. IPv6 succeeded IPV4 and is currently used in directing 90% of internet traffic (Amer AbuAli 2001)
The internet functions by transferring data between different hosts across different networks as specified by routing protocols. In order to transfer the data the protocols require a communicating mechanism and this is achieved by using IPv4 and IPv6. Migration from IPv4 to IPv6 is a cumbersome task because of the large numbers of IPv4 users. In today's world, more people and organizations are using computers in their daily work. This will be hard to switch the IP protocol.
The migration from ipv4 to ipv6 is implemented through step by step by utilizing auto configuration mechanism to eliminate manually configuration. Auto configuration mechanism allows users to mutually benefit from the upgraded IPv4 without affecting their connectivity. This method of migration is called the dual stack technique. Both the IPv4 and IPv6 are run at the same time. Data from IPv6 application in one end is interpreted by IPV6 protocol in the other end (Amer AbuAli 2001)
Sets of simple internet procedures have been implemented fro smooth migration from IPv4 to IPv6 which include progressive and simple transition. Administrators update IPv4 routers one at a time without the need of upgrading other routers concurrent
Administrators use the simple transition method simplifies in communication between IPv4 and IPv6. Networking devices which cannot be upgraded to IPv6 like the terminal servers can still operate on the IPv4 protocol using the transition model. In order to migrate from IPv4s, administrators first survey the networking provider in order to establish and analyze the IPv6 workforce. For the IPv6 to be of high quality the network providers provide node to node IPv6 tunnels then vary various traffic based classes using various techniques.
Networkers are also using dual stack with domain name system (DNS), this is done by coding an application to rely on the DNS. When a user wants to establish a connection to a certain server, the server will forward DNS query to DNS server.
Internet providers also use the tunneling techniques, which uses an existing infrastructure to transmit a network protocol. IPv6 signals are transported over IPv4 by encapsulating IPv6 packet with IPv4 header. Some networking providers do this by switching the signal by using tunnel broker approach
In most cases administrators use a mechanism of configuring different end points that are dual stocked. This ...
