What is Internet Protocol (IP)?
Introduced by Vint Cerf and Bob Kahn in 1974, Internet protocol (IP) is the principal for communication protocol of sending data from on device to another across the network utilize the Internet Protocol Suit (usually use TCP/IP). It specifies the address of the device or computer in a network to send to or receive data from.
What is IPv6?
IPv6 stands for “internet protocol version 6”, it is the latest version of the internet protocol (IP) designed for replacing the current internet protocol version IPv4.
IPv6 is developed by the internet engineering task force (IETF), it is referred to as the “next generation protocol”
because of its higher capabilities and wide range of IP addresses. IPv6 uses a 128 bit long address, allowing addresses which allows large number users and computers or other devices to communicate as compare to IPv4 which uses 32 bit long addresses by allowing addresses. It will not only provide a wide range of IP addresses but will also provide other features such as improved routing traffic and security.
Why the internet needs IPv6?
The main reason that we need IPv6 is that range of IPv4 addresses are running out. The internet has experienced a remarkable increase of the devices using the internet, as nowadays computer, phones, video games consoles, cameras and many more devices are joining the internet.
By looking to this extraordinary growth in technology the remaining IPv4 addresses will deplete nearly in the future. IPv4 provides approximately 4.3 billion addresses but the world population exceeds 7 billion, so it seems that at some point we will run out of the IPv4 addresses and once these all addresses are assigned so no other devices will be able to connect to the internet. To overcome the concern of the depletion of Ipv4 addresses IPv6 has been introduced.
IPv6 the replacement protocol of IPv4 provides about 340 trillion, trillion, trillion addresses, which is extremely large numbers of addresses as compared to IPv4 addresses. These numbers of addresses are quite enough for many decades to come on.
Features of IPv6
Some of the major features of IPv6 protocol are as follows.
- Better security
- Header format simplification
- Vast range of address space
- Auto configuration mechanism
- Mobility
- Scalability
- Better protocol for adjacent node interaction
- Extensibility support
