Internet Protocol Version (IPv6)

Internet Protocol (IP)

IP (Internet Protocol) is a set of rules that govern the way data is transmitted over the internet. It is responsible for routing data packets between devices on a network, and is used by all devices connected to the internet, including computers, smartphones, and servers.

There are two versions of IP currently in use: IPv4 and IPv6. IPv4 has been the primary version of IP used on the internet for many years, and it uses 32-bit addresses to identify devices on a network. However, as the number of devices connected to the internet has grown, the number of available IPv4 addresses has become scarce. To address this, Internet Protocol Version (IPv6) was developed to provide a larger number of unique addresses (128-bit) and to improve the internet infrastructure.

IP is a network layer protocol in the OSI model and it works in conjunction with the other layers to transmit data between devices. The IP is responsible for the addressing, routing, and fragmentation of the packets while the other layers handle functions such as error checking and data encryption.

(Internet Protocol IPv4)

IPv4 (Internet Protocol version 4) is a protocol used for communication on the internet. It is used to identify devices on a network and route data between them. IPv4 uses 32-bit addresses, which allows for a total of about 4.3 billion unique addresses. Due to the depletion of available addresses, IPv6, which uses 128-bit addresses, is being adopted as a replacement for IPv4.

(Internet Protocol Version (IPv6))

IPv6 (Internet Protocol version 6) is the successor to IPv4, and is designed to address the limitations of IPv4, including the depletion of available IP addresses. IPv6 uses 128-bit addresses, which allows for a vastly larger number of unique addresses compared to IPv4 (about 340 trillion trillion trillion). IPv6 also includes improvements in security, mobility, and autoconfiguration capabilities. It is being adopted by organizations and service providers worldwide, but it is not yet fully deployed. Some devices and networks still rely on IPv4 and may require translation in order to communicate with IPv6 devices.

IPv4 and IPv6 are both Internet Protocols that are used for communication on the internet. They have some key differences:

• IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses. This means Internet Protocol Version (IPv6) can support a much larger number of unique addresses, which is necessary as the number of devices connected to the internet continues to grow.
• IPv4 addresses are written in a dotted decimal notation (e.g., 192.168.0.1), while IPv6 addresses are written in colon-separated hexadecimal notation (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
• IPv4 has a limited number of addresses (about 4.3 billion) and with the increasing number of devices connected to the internet, many of these addresses have been assigned, IPv6 addresses are much more available.
• Internet Protocol Version (IPv6) includes built-in security features, such as IPsec, which are optional in IPv4.
• IPv6 includes autoconfiguration capabilities, which make it easier to set up and manage networks.
• IPv4 and IPv6 are not directly compatible and some devices may require translation in order to communicate with devices using the other protocol.

Overall, Internet Protocol Version (IPv6) is the next-generation internet protocol that addresses the limitations of IPv4 and provides more addresses, improved security and better management of networks.

Internet Protocol Version (IPv6) In Bangladesh

IPv6 adoption in Bangladesh is still in its early stages, but there have been efforts to promote and implement the protocol in the country. The government of Bangladesh has recognized the need to move to Internet Protocol Version (IPv6) in order to address the depletion of available IPv4 addresses and to improve the country’s internet infrastructure.

The Bangladesh Telecommunications Regulatory Commission (BTRC) has announced plans to allocate IPv6 addresses to internet service providers (ISPs) and to encourage their use. The BTRC has also been working with the Asia Pacific Network Information Centre (APNIC) to provide training and support to ISPs in Bangladesh to help them implement Internet Protocol (IPv6).

Some ISPs and organizations in Bangladesh have already started to implement Internet Protocol Version (IPv6), but it is still not widely used in the country. However, with the increasing pressure on IPv4 addresses and the government’s efforts to promote IPv6, it is expected that the adoption of IPv6 will increase in the near future.

It’s important to note that while Internet Protocol Version (IPv6) is being implemented and adopted, IPv4 will still be in use for a while and it’s necessary to have a dual-stack infrastructure, meaning both IPv4 and Internet Protocol Version (IPv6) will be used until IPv4 is phased out completely.
