Free IPv6 is in demand recently as it provides an advantage over the earlier IPV4. It rectifies the problem of IPV4 which was address exhaustion. It uses 128 bits for address thus allowing more addresses. It is an improvement over the 32 bit IPV4 which allowed 4.3 billion addresses. The major issue with IPV6 is that it is not interoperable with IPV4 which makes the transition a bit complicated. This has led to many new mechanisms being developed for communicating between these two protocols.
Main Features of IPV6
IPV6 is a protocol for the internal layer which provides for the packet switch internet networks. The free IPv6 transition is being provided by many companies so that you can reap its benefits. The benefits of switching to IPV6 are much more than additional addresses. The most important factor is that it allows for automated address assignment without changing the network connectivity. Processing of packets is also simplified with this protocol.
The main issue is the communication between IPV4 and IPV6. Since IPV6 creates a parallel independent network, the communication requires translator gateways. There are several translator gateways which provide free communication using a mechanism like NAT64. There are also other methods to communicate known as tunnelling mechanism like Teredo and 6to4. This is required due to the difference in the two protocols in bytes; the IPV4 being 32 bit and IPV6 being 128 bit.
Use tunnel Broker services for Free IPV6
Free IPv6 is provided by tunnel brokers who provide the transition from existing IPV4 to IPV6. To use these tunnel services the first thing required is a host with the IPV6 capability or having a router with the existing IPV4 connectivity. The tunnel is not a stable platform for communication but is more popular than other mechanisms as it is free. With new technology, the tunnelling is becoming stable providing a cost-effective alternative.
The disadvantage of free IPV6 to IPV4 tunnelling is that they do not provide security features like DDoS protection which is a must for enterprises. However, there are many advantages of the tunnelling services which include (1) You can create tunnels for communication over geographically diverse servers which enable you to use the service anywhere. (2) You can get your own 48-bit prefix after tunnel services are up. (3) You can view the activity using the IPv6 BGP4 and the routing table.
IPV6 is the Future of Internet Protocol
IPV6 is not very common right now and very few ISPs and websites support it. But using it has its own advantages which are indeed the future of Internet Protocols. The most exciting advantage is that you can access your machine from anywhere and your own computer can be converted into a public server! Another feature which is a big thumb up for gamers is that you can play multiplayer games easily as everyone has their own IP.
