Your internet, like ours, uses IPv4 internet. IPv4 stands for Internet Protocol version 4, and it is widely used to connect network devices to one another. Each device uses a specific address, based on IPv4’s 32-bit internet address format.
Private and public internet addresses combined have a total of around 4.29 billion addresses, almost all of which are nearly exhausted. IPv6 addresses like 2001:0db8:85a3:0000:0000:8a2e:0370:7334 are based on 128-bit formats and can accommodate much more. More importantly, IPv6 is more efficient than IPv4.
The everyday private internet user in Bangladesh has either a 16-bit address, 192.168.0.0 – 192.168.255.255 or 20-bit address like 172.16.0.0 – 172.31.255.255 or a 24-bit address ranging from 10.0.0.0 – 10.255.255.255, all based on IPv4 protocols.
IPv6 was initially launched in 2011 to raucous praise, and the following year began to be adopted by most websites. It is estimated that all IPv4 addresses will be exhausted before 2018 is out.
The Dhaka Tribune made some inquiries and discovered that some of the most trusted broadband internet service providers (ISP) like Link3 Ltd, Mazeda Internet, Dot Internet, and Doze Internet do not provide IPv6 internet. A Doze representative said there are plans to begin shifting to IPv6 sometime around March. A Link3 representative said their addresses are a mix of IPv4 and IPv6.
Infolink BD is the first ISP in Bangladesh to commercially offer IPv6 internet. The Baridhara-based ISP offers connections to Baridhara, Banani, Bashundhara R/A, Dhanmondi, Gulshan, and Uttara.
Infolink offers internet packages for home and corporate internet. They offer real IP and dedicated bandwidth for every package. As Infolink is the first to offer IPv6 connection in Bangladesh, it is quite an endeavour to offer something the world is getting acclimated to gradually.
The pioneer ISP now looks to break new grounds with their services as they expand across the city.
