IP stands for Internet Protocol which is the digital address that every network connected device has to share data with other devices through the Internet connection protocol. Standard IP addresses are formatted with 4 different groups of digits. They are limited from 0 to 255 separated by periods.

The IPv6 protocol was developed by the IETF and approved by the Internet Corporation for Domain Names and Numbers (ICANN), with the function of implementing a location system for computers and routing traffic on the Internet.

History of IPv6

Previously, the IPv4 protocol held a “unique” role in the field of network connectivity. The IPv4 protocol is defined as follows:

IPv4 (Internet Protocol version 4) is the fourth version in the evolution of Internet protocols. IP – Internet Protocol, is a protocol of the TCP / IP protocol stack of the Internet layer, corresponding to the third layer (network layer) of the OSI model.

However, with the strong explosion of the “Internet revolution” has led to the risk of not ensuring network security as well as lack of access space. If action is not taken in time, the computer will not be able to connect to the network. Therefore, the need to upgrade and improve the protocol system becomes urgent.

In the early 1990s, the IETF decided to develop a new protocol. This protocol takes the name IP Next Generation (IPng). In 1998, this protocol was officially successfully standardized and approved by ICANN, allowing use in the market, and was named IPv6 (RFC 1883).

The birth of IPv6 has solved the inadequacies in the internet system that IPv4 lacks, thereby creating a leap forward in the digital era.

Improvements of IPv6 compared to IPv4

IPv6 has outstanding improvements compared to IPv4, the first of which is the expansion of the number of access addresses. With IPv4, the access space is 32 bits, which corresponds to 4 billion addresses. By IPv6, the IP space has been expanded, with the number up to 128 bits, many times larger than the “predecessor”.

In addition, IPv6 also has other functions such as:

• Increased security
• Increase Routing
• Configuration is much simpler than IPv4.

What are the benefits of IPv6?

IPv6 is the most commonly used protocol today with many special benefits, including:

• Expand the access space, with the number of up to 128 bits, corresponding to billions of access addresses.
• The arrangement of the title format is more reasonable and optimized, thereby helping to ensure more information security.
• Easier TCP/IP management.
• Routing ability, good configuration and more stable than IPv4.
• Better support for mobile devices.

DNS servers can access websites using domain names instead of IP addresses. But you can still enter the IP address instead of part of the URL. For example, you registered the domain matbao.net with 24.235.10.4 as part of the IP address, 80 as the port name. At this time, you can still access the website using the link http://24.235.10.4:80.

HTTP://[2001:0f68:0000:0000:0000:0000:1986:69af]/

Users can access the website by entering the IPv6 address in the URL. With this method, the URL structure will be http:// addressIP: portname. Note that IPv6 addresses contain a lot of “:” signs. Browsers typically consider the “:” to open ports. As a workaround, IPv6 addresses are distinguished inside brackets when used as part of a URL. For example, if you used a sample IPv6 address in a URL:

HTTP://[2001:0f68:0000:0000:0000:0000:1986:69af]:80/
