Understanding IPv4 To IPv6 Tunneling - IPv4Mall

IPv4 to IPv6 tunneling is a term that relates to the use of the current routing system of the IPv4 address to accommodate the IPv6 traffic. This tunneling helps to effectively migrate to IPv6 by maintaining consistency with the IPv4 routers and hosts that are presently configured. Moreover, you will be able to boost the transfer process to IPv6 by conserving continuity among the infrastructure systems. This is because when you are using IPv6, you will also be able to use the IPv4 networking infrastructure to optimize the available resources. Transition Mechanisms Available Several variants of transition mechanisms are currently available and they are: Semi-automatic tunneling ISATAP tunneling IPv6 over IPv4 GRE tunneling Fully automatic IPv6 to IPV4 tunneling Manually[...]

The consistency with the deployed IPv4 routers and servers is the crucial factor behind a smooth IPv6 transition. An IPv6 connects remote IPv6 locations with an IPv4 network through an IPv4 tunnel. The implementation of IPv6 over IPv4 will support businesses and service providers who are involved in offering end-to-end IPv6 service without the need to have many infrastructure improvements.

Routing and Multicast Routing in a Network

Routing and multicasting are terms which you will often hear when the discussion is related to networks. Both are separate processes and combination of them is used in multicast routing. Routing is a process of sending the data packets to the destination by selecting appropriate route of it. In a network, the data to be sent is broken down into smaller interrelated packets. These packets are usually assigned serial numbers. Then, these packets are transmitted over the network. The links between the source and the destination are a long sequence of links, each maintained by a device called router. It is the job of the router to decide what route will be appropriate for the packet to be transmitted. This decision depends upon many factors, like traffic or routes, efficiency of the route (measured in terms of cost), urgency of the packet, distance of route etc. when the router determines this; it then forwards this packet to the next router.

Multicasting is also a term often used with networking concepts. It is a process in which information is received or “heard” by the listeners who actually need the information. This is different from the broadcasting. In broadcasting, the transmitter just transmits the information to all the listeners. It doesn’t matter if the listener is willing to listen the information or not, but the information will surely reach them. These two processes are used simultaneously in the Multicast Routing as implemented in several networks. The receiver router multicasts the information about packet, and the router who are free to forward this packet responds to this information.

Need for IPv4/IPv6 Transition

The older version of IP addressing scheme was called IPv4, as it uses 4 octets of 8 bits each; while the newer version is called IPv6, as it uses 6 octets of 8 bits each. This changing of IPv4 to IPv6 is called IPv4/IPv6 Transition. Now, since the v4 uses 4 octets of 8 bits each, so there are total 232 IP addresses possible. In contrast to this, the IP v6 scheming have 6 octets of 8 bits each. So, it allows 248 unique IP addresses. This is a big reason for the IPv4/IPv6 Transition, as it gives much more options for available IP addresses. Also, more security and performance stability is added in the data packets which are used in IPV6.
