What is IPv6?
IP address is your digital identity. It’s a network address for your computer so the Internet knows where to send you emails, data, etc.
IPV6 means Internet Protocol Version 6. This is the latest communication protocol that provides identification and location for computer or devices on network and routes traffic across internet.
IPV4 means Internet Protocol Version 4. This is most successful using protocol on network.
Example for IPV6 Address is fe80:cft7:b16:2817:b24a:1dd7
Example for IPV4 Address is xxx.xxx.xxx.47
To avoid the future exhaustion of IPv4 addresses, IPv6 was developed in 1995. IPv6 addresses are defined as 128-bit numbers, which means there are a maximum of 2128 possible IPv6 addresses. In other words, there are over 3.402 × 1038 IPv6 addresses – a much larger number.
The world had progressed quite a far from ARPANET and the scientific communities had realized that the need of connecting more and more devices was inevitable. Thus came the need for more Internet addresses.
In addition to solving the IPv4 address depletion problem by providing more than enough addresses, this large number offers additional advantages – every device could have a globally routable public IP address on the Internet, eliminating the complexity of configuring NAT.
Internet Protocol version 6 (IPv6) was developed to give support to an almost infinite number of devices. It uses 128 bit address, allowing 2^128 (3.4 e38) devices to successfully transmit packets over the Internet. With this powerful addressing mechanism, it was now possible to think beyond the traditional communication over the Internet. The availability of more addresses opened the way to connect more and more devices. Although, there are other limitations in expanding the number of connected devices, addressing scheme opened up significant ways.
What is IPv6?
Originally we uses a 32-bit number known as Internet Protocol Version 4 (IPv4).Here’s an example IPv4 address:
25.59.209.224This protocal is still used today. However, there are limits. Due to the enormous growth of the internet we reach the limits of thouse addresses.
IPV6 is internet protocol version 6.A new protocol IPv6, using 128 bits for the address, was developed and standardized by RFC 2460 in 1998.
An IPv6 address consists of eight groups of four hexadecimal digits. Here’s an example IPv6 address:
3001:0da8:75a3:0000:0000:8a2e:0370:7334IPV6 has been developed to replace IPV4 which is running out of addresses.
Types of IPv6 Address
Now that we know about what is IPv6 address let’s take a look at its different types.
1.Unicast addresses
It identifies a unique node on a network and usually refers to a single sender or a single receiver.
2.Multicast addresses
It represents a group of IP devices and can only be used as the destination of a datagram.
3.Anycast addresses
It is assigned to a set of interfaces that typically belong to different nodes.
Advantages of IPv6
Reliability
Faster Speeds: IPv6 supports multicast rather than broadcast in IPv4.This feature allows bandwidth-intensive packet flows (like multimedia streams) to be sent to multiple destinations all at once.
Stronger Security: IPSecurity, which provides confidentiality, and data integrity, is embedded into IPv6.
Routing efficiency
Most importantly it’s the final solution for growing nodes in Global-network.
Disadvantages of IPv6
Conversion: Due to widespread present usage of IPv4 it will take a long period to completely shift to IPv6.
Communication: IPv4 and IPv6 machines cannot communicate directly with each other. They need an intermediate technology to make that possible.
