Internet Protocol version 6 (IPv6), also known as Internet Protocol next generation IPnG in short, is a standardized method for transmitting data in packet networks, especially the Internet. In these IPv6 networks, the data is sent in packets, in which after a layer model control information of various network protocols can be transferred. IPv6 is a network layer protocol (layer 3 of the OSI model) as part of the Internet protocol suite. Further, IPv6 regulates using the addresses the process of packet forwarding between sub-networks (that is routing).
IPv6 is currently most used version of Internet Protocol because it offers a much larger number of possible addresses that threaten to deplete in IPv4. Critics fear a pushing back of anonymity on the Internet.
Reasons why the new Internet protocol IPv6 came
IPv4 has an address space of just over four billion IP addresses, with which computers and other devices can be addressed. In the early days of the Internet, as there were few computers that need an IP address, this was considered far more than sufficient. Due to the unexpected growth of the Internet today, shortages became prominent. For these reasons, in 1995, the work on IPv6 started.
Features of IPV6
The features of IPv6 includes:
- Magnification of the address space of IPv4 in IPv6 with a definite magnification factor.
- Simplification and improvement of the protocol, which is especially important for routers.
- Stateless autoconfiguration of IPv6 addresses, stateful process like DHCP is unnecessary in IPV6, in most cases.
- Implementation of IPv6 standards allows the encryption and verification of the authenticity of IP packets.
Address and URL Notation in IPV6
Internet Protocol version 6 addresses are usually hexadecimal, with the number divided in eight blocks of 16 bits. These blocks are listed separately: 2001:0 db8: 85a3: 08d3: 1319:8 a2e: 0370:7344.
An URL is the IPv6 address enclosed in square brackets : http:// [2001:0 db8: 85a3: 08d3: 1319:8 a2e: 0370:7344] /
Mobile IP is an extension of the IPv6 standards under the name Mobile IPv6.
